Shan; garden view means anything other than Ocean view (east side of main bldg). To the north, you will see part of the resort and part of Wabasso Beach in the distance, on the west side you'll see the drive, accross A1A and over to the undeveloped land on the other side (no parking lot, that's under the resort), and on the south side you'll see the pool, Ebb 'n Flo's and the rest of the resort. There are basically 3 times as many garden view rooms as ocean view rooms.
You may want to try an ocean view room some time (it's worth the points!), as the prospect is truly breathtaking - seriously, when my DW entered our ocean view room for the first time, she gasped at the sight. We've been hooked ever since.
Have a great time, and congrats on getting such good ressies. ANother thought for the rare occasion that you have points to burn would be the Beach Cottages, which are just spectacular. With a group your size (ie one needing 3 inn rooms) you'd fit in nicely. Of course that comes to 45 pts a night, compared to the 24 it's costing you for the three garden view rooms - so only if you really want to impress or you have a lot of banked points that need using up.
