You can fit 10 in the 5BRs at Moondance, but very pricey.
Not directly on the main beach, but Llantrisant (beachcliff.com) will fit the bill.

Moondance and Llanstrissant can both hold 10 in one villa. Both come with a full staff of cook, cleaning person, groundskeeper and in the case of Moondance, also bartender.
Villas can be combined to suit your group size at Beach House Villas (for instance the Beach House has 3 floors usually rented separately but if you take all 3, will have 5 bedrooms, a huge roof deck, 2 smaller decks and a yard in front on the beach). There's cleaning staff included but a cook is optional/extra.
There are a lot more large staffed villa options outside Negril, in Treasure beach, Montego Bay, Ochio Rios, Discover Bay, Rio Bueno, some with private beach, some part of larger resorts (Half Moon, Tryall, etc).
Hi All! thanks for the replies!
MoonDance is way out of budget.. unless I win the lotto!
We typically stay at White Sands and that is on the list to contact. (we've never gone in a group before)!
Just was wondering if there were others. I really appreciate it!
Llantrissant is fantastic if your group wants total privacy. It has it's own beach - not as nice as the main one but workable and only for the villa. I think it only has 4 bedrooms but might have a separate cottage. I have friends who stay there every year and love it, my only beef is no AC or screens.
Another good option would be to rent a few of the cottages at Nirvana. No A/c, but not a problem in January.
Llantrisant has 4 bedrooms and a cottage, can accommodate up to 12.
