I had a similar experience with my guide. I took the tour in Nov. but was not ready to sign anything that day. My guide made a big deal about going to managment to extend the discount you get if you commit that day for three days. I went home, had questions and called my guide still within the three day time period. About a week or so later, I get a message from guide. I return call, no call back. Meanwhile, I do some investigating on my own, get answers to questions and bought resale to get the resort I wanted for less money.
