Kids in college probably won't cut it if they are taking an afternoon nap (unless you're letting them out on the town the night before and they are sleeping it off?)
HGVC actually has a reputation for some of the softest selling in the timeshare industry, so getting out is
usually pretty easy (YMMV). IMO the easiest way to resist is to spend an hour or so at the Timeshare Users Group BBS (
www.tugbbs.com). It is free, and there is a whole forum about HGVC which can provide a lot of background about this particular resort. It will also introduce you to the resale market where "used" timeshares go for 1-10% of their original price. Letting a timeshare salesperson know that you are aware of the resale market is usually a good way to get out of the presentation quickly. HGVC units hold their value much better than most timeshares, but it is still fun to see them justifying why you should pay $40K for something that you can get for $4K elsewhere.
And if you
are tempted, take your time and make the right decision. TS is a great way to go, but there is a glut of available units on the market right right now at bargain basement prices, with no sign of abatement. Your options are pretty much unlimited, so you have time to research, explore options, and plan at your leisure for the perfect purchase for you. We did that and happily own 3 weeks of usage in Orlando that cost us pennies.
Finally, if you are EVER pressured into signing, remember that there is a rescission period where you can (and should) back out. 99.9% of the time it does not make sense to purchase from the developer, so the chances that the
best decision was made are pretty small!
