I have been to the supper club twice - the first time on the Spirit was 30 dollars and truely an experience! The music was just beautiful, the atmosphere was awesome and scenery outside was breathtaking. We left more of a tip than our two dinners combined!
. The second was on the Glory and likewise was a great experience, however not near as nice as the spirit (although I know all is different). What I didn't like was that we had reservations for 6 pm and the supper club was right underneath the basketball court and all you could hear were balls being bounced. Along with that it was dark inside (dusk outside) and I would have much rather had the window shades open to see the blue water. The music didn't play much, but we still enjoyed ourselves. 16 people is a lot of people, but I am sure they can put you close together as possible. They won't charge you until the end. The cost on the Glory was also 30.00 pp also which did not include any drinks you may have wanted from the bar - and gratuity (optional, but considering the service/food - can't see anyone NOT giving one. ) HOpe this helped.
OH...and to add to what the other post have been about --dress code. If is on a formal night, they request dress up with ties for males. Other nights do not require ties. We went and wore dark jeans/nice shirt and got great service and food! PS...do not eat ALL day on the day you go - you will be rolling out stuffed!
