Just my opinion, of course, but:
I like GV better than many (not all) of the WV room views. I would pay money to avoid looking at that gravel roof and Storm Along Bay! GV is less expensive as well. Bonus!
I moved to WV once from a standard view. It was a terrible idea! We will now only book WV at YC/BC if it is the only room type available. GV is my personal favourite, standard view is second choice and WV a distant third. In fact, if wv is all that is available, I would check out the BW or the Swolphin before booking YC/BC.
There are a few rooms with beautiful water views, but getting one of these is not guaranteed. If you are lucky enough to get one, then it is worth the extra cost. But the risk of the pool view plus the added cost isn't worth it, IMO.
Personally, I think that they should have a pool view category and price it out similarly to the standard view. I am still angry about how much I paid for 2 rooms with that wv (pool view) at YC CL.
