The Tropicana gets my vote. I have stayed at: BWPPI, Tropciana, Hojo and Camelot for my offsite trips. The Tropican room seemed more updated than the others, the bathroom was nice and new. Also the proximity beat out the Hojo as did having a free breakfast. I do agree the free breakfast is nothing great but its free and it was enough to get our day going and save us a few dollars on our food budget. The parking was much better here than at the BWPPI, and they let you take breakfast items back to the room, which BWPPI did not. And it had less of a parking lot feel than the Camelot did. The Hojo is very nice, our room was more spacious than the Tropicana one. However, when I stay offsite its all about location. So even though the walk is not that bad, to me it was just a bummer to pass by other motels that were closer. Because other than the pretty grounds, to me the Hojo is a just a motel too. So I might as well stay closer is my theory!
Good luck, you cannot go wrong with either. And the Hojo does have a baby pool and kiddie spray jets so if you have little kids that would be a huge factor.
