Just wanted to take a moment and say what an excellent job the guys (and girls) at JacoVIP did for us for my best friend's bachelor party last week. They're knowledge prior to arrival helped considerably in the planning and making sure we avoided certain tourist hiccups.
In addition to that, everything they said was going to happen did, and more. The accommodations at Casa Blanca were awesome and where we had an A/C problem in one room the first night (unforeseeable on their part), they were quick to get it fixed and keep us cool and comfortable the entire time.
Maria was our concierge and if you are lucky enough to have her taking care of your group, you are in for a real treat. Everything from buses being on time to pick us up and take us wherever we wanted to go to grocery and alcohol delivery. Everything was quick and easy to have accomplished.
My business is a tour operator that runs very large trips for American football and baseball fans. In my opinion, it's rare you run into an organization that "does it right" and these guys do. They will come highly recommended and anyone who has the opportunity to travel with them should take the worry out of doing it yourself and let them handle it.
