My 2 cents 
The Villages Health System = convenient, cost effective and good choice when healthy. As health issues / problems develop (and they will) you may have restricted medical options or options that are expensive. The advertising in local paper explaining how wonderful TVHS is, is included in the cost of the newspaper at minimal cost to you. Perhaps a Good cost effective option for Frogs (here till you croke ) but not Snow birds (up to 3 months) or Snow Flakes (not full time but more than 3 months and going back when there is no chance of snow).
Medicare Supplement Plan = more expensive but includes the option to get the best medical treatment (where ever) if needed and desired. The more issues you have or don't know about yet, travel, the more this plan seems to makes sense.
If I had the choice I would opt for not having any significant medical issues - unfortunately neither of the above plans offers me that option.
Right or wrong
Got that off my chest so now I can take my nap
