As others have said, it's a personal decision, but we leave for the Gulf Coast in a couple weeks, and I can't wait (this will be our 8th winter of snowbirding). We live in northern Michigan, so there's not a heck of a lot for me to do here until April, other than shovel snow and bundle up to walk the dog twice a day. Down south, I will be kayaking, fishing, walking around town with just a light shirt on, sitting outside in the sun by the water, grilling dinner outside.......it's great. I can't recall ever being bored down there. Absolutely no comparison to staying here for the next few months. As for the cost, we have a travel budget and just look for a rental house that fits the budget (for the length of time we want to stay). Once we've committed the money for that, and budgeted for other stuff like food and entertainment, I don't even give cost a thought after that......I just enjoy myself.
