We stayed at Summer Bay last December. It was a wonderful resort overall, and I am looking forward to a return visit. The condos were spacious, tiled floors, adequate kitchen, pretty grounds, a number of pools. We did not participate in activities, but we did go over to Kareoke Night. (Oh, that was pretty bad, but that's kareoke I guess.)
It is just a little further out on 192, so a bit more of a drive to WDW, but not that much of big deal.
In addition to the Publix, there is a brand new SuperWalmart very close by. Prices were better, and hours were more accomodating. It is maybe another mile and a half, but it was worth the effort. (I am an early riser, and I wanted to get some odds and ends before the day started. When Publix wasn't open, I dashed over to
Walmart - I had shopped, home, and all put away before the official Publix opening.) Just go north on US-27 toward Clermont about a half mile, and it is on the right, set back from the road a little. It had just opened when we were there in December.
In the Publix shopping strip, there is/was an internet cafe, and a nail shop. I didn't personally use these, but they were recommended on other bulletin boards.
