Can tourists' book into a Shenzhen hotel without a visa in shenzhen? Do they sometimes make exceptions if you have flown in to Shenzhen airport at 00:40 that morning? Can anyone help?

Can I obtain a shenzhen visa at shenzhen airport? I arrive at 00:40 on Monday 29th December 2014. Does anyone have any good advice?

I have booked a room at jinjiang inn on Sunday 28th December 2014, however, I will arrive at Shenzhen international at 00:40 and would like to know how to get to jinjiang inn. I'm guessing that a taxi would be the only option. How much would I expect to pay in RMB? How do I prevent being scammed? Where is the best place to hail a taxi? Bearing in mind I have never been to mainland China before. I have heard that Shenzhen taxi drivers aren't averse to scamming unsuspecting foreign visitors. Forearmed is forewarned. What is the immigration procedure at the airport? ( I'm a British passport holder). Will I be able to change currency (from HK dollars to Chinese RMB) at the airport to pay for the Shenzhen visa. I am flying in from Japan. What is the cost of a Shenzhen visa in RMB for British passport holders. Is that procedure easy and simple? Thanks in advance for your responses.
