I've said this before, but recently I've received a lot of e-mails about "things that were promised", so I thought I would repeat it.
Read every document you receive when you buy a timeshare, no matter who you purchase it from. Take your time with the documents. Ask questions if you have them.
If something was promised to you, get it in writing. If someone won't put it in writing, assume that it is not true.
Of course, these caveats go for all purchases, timeshare or not, but unfortunately, there's a lot of "ether" floating around timeshare sales rooms and timeshare websites.
Read, understand, get it in writing...and then have great vacations.
