Marriott 'Floating Week's ?

Is there a list somewhere of what the breakdown of 'weeks' is for Marriott Newport Coast, Marriott Canyon Villas (Phx), and Marriott Maui Ocean Club? It is listed as 'high', 'medium' . Assume that those with a number are 'fixed weeks' -- Christmas.New Year, 4th July, etc. (week 26, Week 52)..

I've seen lists re: platinum/gold... but how does that compare to medium/high? Is Gold = Medium, Platinum=High? Gold=Medium= Jan 1 - Memorial Day (May 28th-ish), Platinum=High= Memorial Day - Dec 31 ???

Found the below......The seasons are approximately as follows: Gold = >Generally after Jan 1 to weekend after Memorial Day. For 2009, first check-in day is Jan 2 Platinum = Remainder of year, except for fixed weeks noted below Platinum Plus = Reserved week which includes July 4. This is a fixed week; same every year. Holiday = The week which includes Christmas and is a fixed week.

What are high and medium weeks
