>>1042867honestly if you're that worried take a roadtrip out of town. you'll get over the anxiety pretty quick
OP, its what you make it really. they're designed for couples and families but generally if you're comfortable in your own skin then you'll be fine. the lounge shows are full of hot women and are generally entertaining, drinks are relatively cheap, sitting on a 'communal table' for dinner chatting with people is pretty interesting too (met a retired engineer from JPL, cattlestation workers, university professors etc)
then go back to your room whenever you feel like it, chill out on the deck with a few drinks and be done with it
be prepared for stewards coming in and out of your room every few hours for various things and to basically be bombarded by infomercials at every turn (they will milk you dry if given half the chance)
