I'm going to Iceland at the end of July for 3 nights. I have booked the flights/hotel/transfer to hotel as a package. But as to how to do other stuff I am clueless and nervous!! how to get to the airport (to Gatwick..I live in Sussex), how do you check in? how much luggage? should I just take hand luggage? how much money should I take? (no meals are paid for yet)? will I be able to use Visa Debit in Iceland?
I'm getting slightly panicky as this is the first time I have travelled (with family) abroad where I've had to organize things myself.
Any advice much appreciated?
