I do not have any concrete knowlage...however, with the teen club advertised open till 2am, it would seem strange that the 'real bars' would close at 1am. I have seen some litirture that states (something like) "open 9pm-wee hours". So, Id say they'd be open at least till 2 or later.

Usually... most of the cruise compasses say the bars are open late. I have been in some where they were open till 3am. When on Adventure... we drank in the Viking Crown Lounge bars until 3am (it was tough getting up the next morning to go scuba diving in aruba at 8am!!)
From my experiences... the casino and bar in casino is usually open until 3am. The disco is also usually one of the last bars to close as well.
