Hot tub decision. If so how big and where to put it?

[Annette Holbrook]

I have a cabin in the North Georgia mountains. A hot tub seems to be common in the higher end rentals. The cabin closest to mine does offer one. I’m trying to decide if it actually is a draw and will get used. I mean it is still Georgia, and summers are super hot. So I’m guessing no one wants to sit in hot water when it is 80-90 degrees, but as I’m not a big hot tub person so what do I know? 
Assuming it is determined it is a good addition to the property, how big do I go. The cabin can sleep 8 adults comfortably, or maybe 10 if they use the fold out sofa. I’ve read that really big hot tubs are very time consuming to clean, refill, and get up to temp so I was thinking a 4 or 6 person tub max. 
Last issue, where to put it. I have a lower screened in porch that is down a flight of stairs from the main living area. With some landscaping, you will be able to see the river while in the tub. Of course, the screening is for bugs which are mainly an issue during the summer, which is probably not the most popular time to use the tub. But it will be protected from the elements which may be helpful in maintenance. I could also find a flat area outside just off the screened porch that is overlooking the river. 
Thoughts?
