We were also trying for the Beach Club late July, early August this year, with rented DVC points. Unfortunately there were only a few days of availability for studios and we didn't want to start hopping all over staying at 3 or more resorts. We luckily were able to find a 7 night confirmed DVC reservation at the Boardwalk for our first 7 nights (thank goodness they at least got rid of the clown face at the pool), then we have a Polynesian lake view for the last three nights.
We're trying to figure out if we need waterpark tickets or not, since the deluxe resorts have such nice pools. I really wish we could have been able to secure a beach club stay but it wasn't in the cards. BC has such an amazing pool area. Either way, we're just thrilled to be able to stay in that general area (Beach Club, Yacht Club, Boardwalk) for the first time. It's my favorite area in all of the WDW property. Just love the setting and the ease to EP and HS.
I'm praying for a good lake view villa at the Polynesian too. Hope you have good luck with the Beach Club.
