Stop in for a cup of coffee

Latest new idea from the recent retiree is a hot tub on the back patio. I agree we need one.
We've never had one. Friends have one never heard any complaints.
Anyone here had experiences with them?

I hear the same, upkeep - stay on it. I also hear they can be expensive to run year round, but it is awesome sitting in one, outside at night in a snow storm when it is cold out!!
