Hi Cesar, We are very sorry you had a rough ride to start your beach trip! When we provide shared shuttle service we do our best to be clear with our passengers that the vans make a number of pick-ups in Antigua and there may be a wait. We are sorry if this wasn't communicated clearly enough to you and if the driver said he did not get the message when we had inquired about his ETA. The shuttles in Guatemala tend to vary in terms of what interior amenities they provide, and a lack of AC would have certainly been frustrating while the shuttle was making those stops you mentioned. We will inquire with our provider and let them know our customer was dissatisfied, and we apologize for your experience.
