I would recommend that you don't go to anyone, unless you have a very strong will that will not let you succumb to pressures and harassment from an agent. I have been in a Timeshare "orientation" and they work you endlessly in order to conquest you. They will play with numbers... how much yo spend on vacations, how many vacations you have in a year, and so on. They play mathematical tricks on you so you can get the impression that this is a good idea. They will not let you to analyze nor to make your own budgetary analysis, neither to let you take time before you make your final decision.
I have friends who have lost thousands of dollars in the timeshare scheme.Timeshares are a rip-off, don't buy on it.
