We did the snowbird thing for 3 winters in central FL - from Michigan... from 3 to 5 months.
I’m not retired, but have worked from home for many years - as long as I have internet, I can work.
If you are ‘work dependent’ on internet, I wouldn’t rely on campground WiFi. Extenders can help if not close to tower, but nothing fixes the poor bandwidth many have.. or an off hours outage needing access to campground gear.
I used an unlimited hotspot (AT&T Mobley), with a cell phone hotspot (Verizon) as backup and worked from the passengers seat of our Hurricane.
Why did we stop? Like Mr Sunshine we moved to FL full time.
