I would still only consider single family as the condo, hotel, & resort rooms are in a far worse over saturated situation.  

They don’t have issue at hotel for gym, pool, hot tub but a house has a different mind set of privacy. 

High quality hotel brands are owned by investors and  triple net leased to management companies.

I worked for IHG, the hotel chain, and if you are a franchisee, the home company can easily remove your status as a franchisee. 

If you do go with a non-connected lock please change the codes often, I often compare it to a hotel in that if the front desk told me the previous occupant's keys still worked during my stay I'd be sort of annoyed.FWIW, we use ResortLock from Lockstate (no affiliation, just what we use) on all our properties. 

But it's kind of like saying "does anyone want to back me in building a five star hotel" which you're probably not going to get any traction, unless you have a track record of working for a five star hotel developer for a few years and can demonstrate you truly know how to execute that type of development. 

Sometimes people don't want to stay in a hotel and would rather stay in a home!

Below you can find a quick FAQ sheet of the updates they have implemented and will be implementing soon.Quick Overview: - The cost of application fees has increased- Platforms will remove listings without legitimate permit numbers- Platforms will have to remit the Hotel taxes directly to the city of San Antonio (Operators still have to file revenue reports monthly)- STR operators can change the operator of the permit without a new application being required (it seems the permits are still non-transferable upon sale, however)- Updated Party Prevention measuresMy Take:This should weed out some hosts that have not been abiding by the permit requirements.

They can get a hotel room.

@Terri-Leigh H.the hot tub is similar, bench style, to what is found at ski resort hotels.
