Hey Ravi, I managed five units in the Poconos.
1.Patio vs. basement installation for the hot tub? Patio for sure. Indoor hot tubs do not have the appeal that guests look for when they go to this market.
2.How to run the hot tub without guests for a few winter months (avoid headaches)? Hot tubs will increase winter bookings! Keep it running
3.Hot tub maintenance for short-term rentals: cleaning & water changes? Cleaning after every guest, only need to dump it when a guest makes a mess. If this happens, we charge guests. Usually its lotions but i've also had guests do nasty stuff and or add dish detergent to the hot tub (they said it wasn't clean and thought that might help ha!)
4.Hot tub: value-add or headache for Pocono STR? I know this market, you wont get many bookings without one. Hot tubs in the poconos are a must unfortunatly because a lot of people have them. If you want to stand out from the crowd, consider outdoor shower and barrel sauna as well.
