Four days will go by in a blink of an eye. Take the trolley tour. If for nothing else, to see how big TV is and get a feel for getting around. Buy a map and study it before coming down for a visit. Hop in the golf cart. and explore.
Talk to anyone and everyone about TV ,and they gladly volunteer all kinds of information. People are very happy and proud of living in TV.
REA will show you to your property, and then leave. You will have to contact them if wanting to house hunt.
Consider renting for a month or two will give you a better feel for TV.
Be prepared to be blown away by the beauty of TV, and it's friendly people.
It's like a step back in time to a gentler generation.
