Can you tell me if the Marriott is the best place to buy time share ?

It is the most expensive

If you want daily maid service it is extra. Buy at a deeded resort like Playa Linda,

There are various types of timeshare ownership plans. You can see a discussion of the on my web site:

Just scroll past the house stuff for this. It includes a financial mode to help you determine if it is better to buy or rent.

I have 3 weeks at Marriott and could not be happier. They are flexible and a top notch organization. You are not tied to weeks only season
