I see a lot of disgruntle time share owners on the internet but for other places, Florida, Mexico, Arizona etc. Maintenance fees start off low and then its sky high. However, in general Aruba timeshare owners are usually happy on account that they are repeat visitors and maybe easier to sell of your week there. A lot of timeshare in Aruba like La Cabana I believe has a bulletin board with owners selling their week which is usually a lot cheaper than buying direct.
Always keep in mind maintenance costs. I own in Kissimmee Florida, started off with maintenance fees of around $300 which today is $1,100 a year. However, I bought 30 years ago and have been trading it to Aruba the last 10 years. The $1,100 maintenance fees is certainly worth it for a 1 bedroom suite at la cabana or Aruba Phoenix. I'm actually entitled to a 2 bedroom as I own a 2 bedroom in Florida but they are seldom available and if I am traveling alone I don't really need a 2 bedroom.
