are you looking for a more club-like atmosphere or something a bit more relaxed? 8 trax does play 80s music on thurs nights and can be a lot of fun. i go to wdw a couple times a year- usually a family trip and then another w/friends. we always spend a few days at pi. is it bad that my brothers and i are known by many of the cast members there- including bartenders, barbacks, security, and foot cart owners? we usually go to motions (plays more top 40 dance music) and 8trax and occasionally bet. we like to dance so we generally go and hang out by the bar and head to the dance floor when we feel like it. there is an irish pub that opened last year- raglan (i think) i haven't been there but would assume that it is more relaxed. mannequins plays techno music and has a revolving dance floor. the adventurer's club is entertaining and is more "interactive". i have not been there in a very long time so i can't comment further. the rock n roll beach club has rock bands often and is very big. you can dance on one floor or hang out on the others. this place does not get too crowded so we'll usually go there for a drink or two to relax. i guess it all depends on what you are looking for. i think that is why we like pi. you can go to whichever place you are in the mood for that night. fyi- thurs (and i believe mon) are cast member nights at pi so it gets pretty crowded. have a great time and congrats on the upcoming marriage!!!!!!!!
