Welcome Cheryl and Cliff.
Our exercise class at Odell is traditionally VERY full in January. (I am way up North right now so...I am guessing.) Check the Recreation News free at any rec center and it will tell you the times. Good advice is to arrive a least 1/2 ahead of time.
You can check for ballroom activities there too, (in the rec news) and even if you can't join, I am sure you can observe. I know that is true of Art Studio.
We didn't look at resales but I have heard that LYLE GANT who advertises on here is good. He certainly has the most information on his web site. I recommend Jim McLaughlin who is a rep for The Villages, but he couldn't be assigned to our friends who came down last year. I don't know how that works.
As for Jupiter Springs, we have never made side trips off campus, once we found TV. I had been most everywhere else in Florida at one time or another and wasn't crazy about any place...until we visited friends in Poinciana less than two years ago. I fell in love with the The Villages. We bought a Camellia in Hadley last June.
I certainly hope the weather is better for your visit.
I take it you aren't golfers. Where are you from?
Hope you have a lovely time.
