HH Studios are the largest at any DVC resort. In this case they are about 100 square feet larger than BCV. Four can still enjoy the other resorts though.
Here are some reported room sizes for DVC resorts:
OKW
Studio: 390 sq. ft.
1 BR: 1005 sq. ft.
2 BR: 1410 sq. ft.
GV: 2375 sq. ft.
Also, the studio balconies at HHI are bigger than the ones at BCV (at least the one we had). At HHI, we had a picnic table and a rocking chair or two. I've never had that big a balcony at BCV.
Darn! Looks like we should shell out for a one bedroom doesn't it. In that case I think we'd be better to skip the dining plan and get a DDE card. We can eat breakfast in the room and maybe swing back from EPCOT for a quick bite and a swim .
