As a previous poster said, NOTHING is worth enduring a Westgate timeshare presentation.
Forget 60-90 minutes. It is a high-pressure, no holds barred presentation that will suck up a good 4 hours of your day. They will insist on taking you out to visit units to try to change your mind, etc.
Their motto is "If you're not buying, you're crying".
If you really want to stay at a Westgates timeshare you can usually pick up "hotel rate" condos for not a whole lot of money and no presentation required. Not that I would ever recommend Westgate again after my experiences last year, but I used to get a 2BR at the Lakes in the April time frame for around $119/night, which includes housekeeping services, with no presentation required.
