That is very sound advice. Thank you!@Dreamweaver101 Welcome to Tug. You are wise to research such a purchase.
You said you are not a detailed oriented planner. Your maintenance fee budget is at the bottom-end of hotel-branded timeshares (and this will increase every year by 2 - 3%). Plus you are upset by the sampler program choices. Given all of this, I don't think you would be a happy TS owner given you are locked into a school schedule for the next 4 years.
Why don't you rent at TUG or Redweek or directly from resorts to get a feel for independent TS (which fit better in your budget) in your desired locations for the next few years. Once your kids are out of the house, you can then see if more flexible schedules at an independent resort would fit your lifestyle, and whether the maintenance fees and upfront cost save you any money vs. renting.
