I did it once and would return but not for more than 2 drinks. This is mostly because the antics occurred on every drink ordered by everyone we saw the krakatoa antic four times before finishing one drink and the nautilus one twice.
It was also pricey especially with the souvenir glasses, which is somewhat understandable but I feel like it should be more subsidized than it actually is. 2 single person drinks ran over $40 with tax/tip. The drinks meant for two or more people definitely didn't look like as good of a deal as CMs were really into the antics and some of the better CMs we had overall the whole trip.
It was still fun and if I went back it'd be for another set of souvenir glasses and the good CM experience. It's disconcerting to see that others in this thread had subpar CM experiences as that was one of the factors of me returning.
Additionally, I don't enjoy drinking in the hot weather so the A/C inside was why we decided on the inside even with the Dole Whip machine servicing the Spikey Pineapple cocktail trying to lure us outside.
