Well, we're back in the real world now for a couple of months (1BR BCV in Oct for my Bday).
Sunday we did the BLT pool for a while, but it was getting a little crowded. So went over to the CT pool - which we liked better. The slide was better than BLT (faster, and smoother - you can feel the seams in the BLT slide when you go down on your back), the pool was larger, and it wasn't as busy.
We finally made it over to the CT a few times, and got to walk the new skybridge floor. For those that haven't been on it, I would describe it as a small pebble-y surface - kind of like a really rough grit sandpaper (not gritty like sandpaper though). I walked on it after rain and in the morning dew and didn't slide around any. The CT "patio" on the 4th floor was closed though - it looks like they put down the same surface out there too, but it was blocked off from going out on it.
Also, it did seem like the door from the CT was requiring the key to open. But I only had to use my key once, as the door was usually open from someone else coming or going. One day it was pretty windy and the doors wouldn't close automatically - the wind was holding them open.
So we stayed 4 nights in the cramped BLT studio, and we did just fine. I can stand by my early observations, we found it to be about like a regular hotel room - it was okay for the 3 of us. The kitchenette/sink combo never proved to be a problem. And I finally figured out what what people talk about when they talk about the gap in the bathroom door - didn't even notice it until about the last day and it didn't bother us. Sure, we'll do a 1BR more often because it's nice to have the extra room. But I could see us going studio here and there if we're short on points or want to go more often than 1BR points would allow.
