We are very disappointed with trip. We had no air-conditioning at all on the trip back. There is no excuse for not fixing or turning the air on. On top of that we were woken up to be asked by the tour guide to give him a tip and to give the bus driver a tip. When some passengers told the tour guide that they only had $3.00 left to give, he told the passengers that there was an ATM machine at the last stop. We all felt very bad that he was telling us we had to tip and on top of that he was telling us how much to give. It was very unprofessional.
