I'm in my late 40's and have been to both parties with other adults within the last few years. I think you will enjoy Bomba's more than Trellis if your goal is an adult bucket list worthy "party".

I'm actually sad I missed attending one "in the good 'ole days". Alas, I was born in the wrong generation. <img src="http://www.traveltalkonline.com/forums/images/graemlins/Wink.gif" alt="" />

Plusses about Trellis - better food, beautiful fire balls, close to boat

Plusses of Bomba's - unique tea tradition, better band for dancing, crazier party crowd with possible "spring break" type antics for entertainment
