even though silver has more weeks?
.
Doesn't matter. If you own Silver then you only get Silver usage.
Think about it. If what you want were to occur then there could be a Gold week owner who would be unable to reserve a week in his/her season because you took his/her entitled week.
This is nothing unique in the Marriott weeks reservation system. You are entitled to reserve a week only during your own purchased season, and if you want something else then you need to use Interval International and hope you can snag a week in a differing season via an exchange.
One other hint: If you own a Gold week at Grande Vista, and if your week is a member of the Florida Club, then at the six month mark you are entitled to reserve a Gold week at Ocean Pointe. That may solve your issue of grabbing a Gold week at Ocean Pointe.
