They are now used as just an alternative to hotels for anyone traveling or even staying for exptended periods of time.

The condotels stopped providing access to the hotel amenities that were paid for by HOA fees and reservation fees.  

If the town has a hotel, there is demand for STRs...count on it!

The biggest challenge isn't the lease length, it's the furnishings.For instance, a hotel room has furniture, but few additional items.Many investors are turning their fully furnished STRs into MTRs. 

I recommend buying "hotel quality bedspreads" which are affordable and available on Amazon/Retailers.  

I want to go a little more high end hotel /spa this time around- although no one ever complained about the sheets I was using. 

MASSIVE infrastructure, massive residential buildings, hotels, restaurants and more.

Only a few buildings in Sunny Isles allow daily rentals AND some that do have restrictions on the time that the owner is allowed to reside there.For condo hotels (most buildings in Sunny Isles allowing daily rentals are condo hotels) you will need at least 35% down UNLESS you buy in a building that allows monthly rentals, in which case likely will need 25% down as none of them are warrentable.

Hotel to Apartment Conversion would help you accomplish your goal in 1 deal.

On the other end of the spectrum, a 100% transient park with daily/weekly rental traffic, will operate and perform more like a hotel.
