I think the reason the Boardwalk Inn gets little attention in the boards is because it's smaller that the other on-site hotels. I'm sure someone has the precise number, but I think the BWI only has about 350 rooms, about 1/10 the size of the Carribean beach. Even including the Villas, it's still smaller than the other resorts.
Moving on to personal opinion (as opposed to facts), the Boardwalk Inn is my absolute favorite resort at WDW. I've also stayed at the Wilderness Lodge, Grand Floridian, Yacht Club, and Carribean Bearch, but I enjoy the BWI above all of these resorts.
The rooms are big and airy. If you have a view of Crescent Lake, you can sit on your deck, relax, and watch the world go by. If you have a garden view room, you can do the same thing looking at a tranquil scene. There are many high quality dining choices within walking distance. EPCOT and the Studios are very close (a 5 minute walk to the international gateway, and 15 minute walk to the Studios, or you can take the boat). Lastly, on every trip I've made to the BWI, I've been treated very well, and any problems have been quickly and pleasantly corrected.
When I'm at WDW, I stay at the Boardwalk. I've done it alone and loved it, and I've done it with my lovely spouse and darling teenaged daughter and loved that too.
Enjoy your trip in July. I'm envious.
