What size hot tub do you use for larger cabins?

[Brandon Gale]

I have a larger size cabin in Pigeon Forge (sleeps up to 10, usually have 8 guests).

My hot tub is on the way out, so I'm starting to plan for replacement but know absolutely nothing about hot tubs.

I've called around and it seems like the most common size is an up to 5 person tub (roughly 70"x80"x34").

Is this too small for a cabin of my size? Should I be looking at the larger hot tubs? seems like the next size up is 6-7, then even 8 person, but the 8 person ones seem much bigger than the ones I typically see at cabins.

Also, what hot tubs do you guys have in your cabins? Is there a standard value brand that many STR owners in the area use?

Any help or insight is appreciated!

Our cleaners told me this is the standard size from their experience in the PF area. 

Our cabin sleeps 23 and no one has complained it is too small.
