Both are good. Although F looks more relevant, if you are a citizen from eligible countries (e.g., U.S., U.K., Canada, Argentina), the advantage for an L visa would be the eligibility for 10-year multiple entry. Please check the Chinese embassy websites for the most updated policy and details, such as here. We have also outlined visa-free policies on the main page.

Schedule (available soon) @ Arrivals Hall A, Group Pick-up Area (pictures 1 and 2)
Here is the official airport webpage with arrival details. In case of a delay or early arrival, we will monitor this page and have known in advance, adjusting the shuttle service when necessary. In case you don't see pickup signs at the arrival exit (Arrivals Hall A, Group Pick-up Area), please give Ms. Leyuan Shen a call (you should have received a final confirmation email with contact info).
Here is the airport's homepage, locations for stores with phone cards, sockets, etc. being a click away. More specific information can be found here (wifi, currency exchange, phone card, etc.) and here (to Hong Kong downtown).

The most convenient entry from Hong Kong SAR to Mainland China is through Shenzhen Bay Port. To reach there, coaches and limo services are offered at the Transport Centre, Hall A of Arrivals Level (L5), Terminal 1. (Among the providers, TIL Chinalink is good.) Once you get through the Shenzhen Bay Port, take a taxi (around 30 min, 50 CNY) from the taxi station to the Genpla Hotel. Beware of scammers for car rides.
If you plan to spend a bit of time in Hong Kong, a recommended route is to take the Airport Express train to Kowloon Station (around 20 min, 105 HKD ticket at entry). The station is located in a mall, called ELEMENTS, with self-service lockers for rental up to 24 hours as well as coaches to the Shenzhen Bay Port (around 40 min, 52 HKD). These services can be found in the waiting area for Mainland coaches on the first floor of Fire Zone (here Fire refers to one of the "five elements"). From this station, you may go anywhere in Hong Kong by metro, or the Kowloon area itself is interesting to explore.
Since after IWoAT 2018, the bullet train between Hong Kong's West Kowloon Station and the Shenzhen North Station has become the most convenient route connecting SUSTech and Hong Kong, a mere 20 minute ride! Tickets need to be purchased separately and in advance.

It takes a 40 minute taxi ride for around 90 CNY to the Genpla Hotel. Follow the signs to the Ground Transportation Center. Beware of scammers for car rides on your way to the taxi station.
If you don't have heavy luggage, the metro maroon Line 11 to Qianhaiwan 前海湾 followed by purple Line 5 is pretty convenient too, but it takes longer (50 min, 7 CNY). Get off at Tanglang 塘朗 on Line 5 and there remains a short walk to either the campus through Exit C or the hotel through Exit A (map).

It takes a 10 minute taxi ride for around 20 CNY to the Genpla Hotel. Beware of scammers at the railway station for car rides.
If you don't have heavy luggage, the metro purple Line 5 is pretty convenient too, just two stops at Tanglang 塘朗 (in the direction of Chiwan 赤湾) followed by a short walk to either the campus through Exit C or the hotel through Exit A (map).
Bullet trains also connect Shenzhen to Guangzhou in 30 minutes.

There are two (slightly different) models running at the same rate: the blue minivan with white roof sign and the blue minivan with yellow roof sign. Both are fully electric but the latter one is rated higher in terms of cabin quality and service (a local stimulus program). Each taxi driver should have GPS on their phone and normally uses it. Make sure the meter is on, and ask for a receipt when you get off so that in case you forgot your belongings it'd be quick to get them back.
The staff at the hotel front desk are happy to assist you to call a taxi. When you return to the campus, Gate 1 is closest to the conference venue.

Here is its website.
SUSTech Gate 1 is close to Tanglang 塘朗 on the purple Line 5 (Exit C).
The most convenient route to downtown Nanshan District is to go west along Line 5 to Bao'an Center 宝安中心 (in the direction of Chiwan 赤湾) and then transfer to the green Line 1 heading east towards Luohu 罗湖, getting off at High-Tech Park 高新园 (or getting off one stop earlier at Shenzhen University 深大 and transferring to the orange Line 13 for Rencaigongyuan 人才公园).
The most convenient route to downtown Futian District is to go up along Line 5 to Shenzhen North Station 深圳北站 (in the direction of Huangbeiling 黄贝岭) and then transfer to the red Line 4 heading south towards Futian Checkpoint 福田口岸, getting off at Convention & Exhibition Center 会展中心.
Free wifi is available on trains. For change to buy tickets, go to the helping desk at each station. Some recent initiatives offer more convenience to international visitors.

Shared bikes are convenient and available outside of Gate 1 of SUSTech (and elsewhere in Shenzhen), but you need to download an app in order to scan and ride them. If you know someone going with you who has one on their phone, they can often scan an additional bike for you, as there are multiple apps for different brands (blue, green, yellow).

It is complimentary to use the shuttle service and visit the whole campus. You can search for the WeChat Mini Program 你科手册 to check the real-time location and timetable of the campus buses.

There are boards, chalks, and printers on the six floors of the Math Department located above the conference venue. Everyone's welcome. Rooms M3009, M4009, M5024, M616, and the commons room M712 are ready to use as long as there are not scheduled seminars or meetings. Feel free to ask for assistance with printing or copying in M4005. You may also send files to Ms. Shen at shenly@mail.sustech.edu.cn and she will help you print them out.

Good for cycling, running, walking, or people-watching. Particular attractions include the Talent Park alongside the iconic bullet-shaped skyscrapper (designed as a bamboo shoot).

This greenway, officially known as Dasha River Ecological Corridor 大沙河生态长廊, is a river trail good for walking, running, and cycling which connects the SUSTech campus (adjacent to its upstream at Changlingpi Reservoir) all the way to the Shenzhen Bay (into the sea), through Peking University's and Tsinghua University's Shenzhen graduate school campuses and past the conference banquet location at MixC World (a 40 minute bike ride).
The University also has several trails on the north part of its campus. In fact, the Shenzhen city, built out of a jungle some 40 years ago, has been reshaping its landscape with parks connected by trails. Ask a local for more info.
