Please recommend a Discover Scuba excursion in Georgetown

My family and I would like to do a Discover Scuba excursion in Georgetown. The excursion that NCL offers requires participants to be 12+ and my daughter will be one month short of her 12th birthday. Can anyone recommend a reputable company to use?

Eden Rock is reputable and the shop nearest the tender landings http://www.edenrockdive.com/instruction.html

I prefer Sunset House which is about 1/2 mile down the road ... few folks want to head "this far" so it is seldom crowded which can be an issue at Eden. Sunset does not list a discover dive but trust me, they do it. Just contact the hotel and ask them to pass your request to the dive shop. I've always gotten a reply within 24 hours unless the boss was off. price is the same as eden. SunsetHouse.com

PADI says the minimum age is 10 but I'd check with the shop to be sure ....
