The decision to buy here or anywhere else is the same rationale as a boat, RV, or expensive pair of shoes.

If you use it constantly or very often all of the expenses begin to normalize into something rational. If you enjoy every time you use it or stay in it you add the great enjoyment factor.

Same with shoes. A 300 dollar pair is wirth it if you wear 150 days a year for 10 years. Conversely, a 50 pair that dont fit and sits on the shelf is a waste.

On the the other hand if the boat sits on a trailer, or RV in storage, or second home never gets visited it just becomes a great expense with lots of unpleasant surprises like a leaking boat, a leaking roof, a burglary or a hurricane.

So, how many months a year makes it worth owning, Id say at least half.
