it is best to take sterling, but they will only take notes and they will have to be English notes in excellent condition. You are best to change your money at the Cadeca. do not change your money at the reception desk you will not get a good exchange rate. Yes they wait to hand you toilet tissue take baby wipes or hand over coins for the toilet paper at the airport. The cadeca at the airport is outside the building and it is a good place to exchange your money.
Check into the VIP lounge on the return journey it is worth it. If you don,t do this refrain from using the cafe on the ground floor it is covered in flies and boiling hot. go upstairs it is a bit better. Enjoy Cuba the people are great and it is a fantastic holiday we last stayed in the Playa Pesquero brilliant Have a great holiday Dolly
