floating week vs. fixed week

I've been reading too much today and have now confused myself. Could someone please explain floating vs. fixed week to me? It was originally my understanding that fixed meant you were guaranteed that week. Now I read something and it seems to be saying fixed is that same room for that same week.

Thanks,
Deb

A unit can be for a fixed week, in which case you always get the same week (e.g. week 27).

A unit can be fixed week/fixed unit, in which case you always get the same unit and the same week.

Logically (and I assume in reality) a unit cannot be a fixed unit without also being a fixed week; otherwise, multiple owners could demand "their" unit during the same week.

My understanding is that Starwood charges a 10% premium to fix the week and an additional 10% to fix the unit as well.

I just bought a fixed week/ fixed unit. This is unusual because my first time share was in 1985 and was a fixed week and fixed unit. The week was nothing special but it was available the second week in April in Hawaii. So naturally, I thought of all the benefits like a fixed week of vacation every year. Easy to know when I went to Hawaii. Couple years later I got a Marriot floating week and suddenly I loved the freedom and flexibility to travel in different weeks.

Recently, I found a ts building in which each of the corner units had a balcony that wrapped around the corner so your bedroom had double balconies and great views. Only 2 per floor faced the golf course and the ocean, so I naturally would not enjoy any other unit and I was picky about my week of travel.

Moral of the story, I own and enjoy a floating TS, a fixed week TS and a Fixed Week and Fixed unit. That is why all the timeshare companies charge more for fixed weeks like Xmas and New Years, and I most tuggers do not own those weeks, but most of us would exchange or trade for them.
