Hi SueP365,
I have looked into it and there are a few others travelling from Gatwick airport so you will not be the only one.
Regarding the ATMs, I cannot say whether the hotel you will be staying in has an ATM machine, but I do know that there are plenty within the area surrounding the hotel, so withdrawing money will not be a problem.
If you have any other questions then please do not hesitate to email me.
Kind regards
Cheryl, your editor
