I've never been to a dueling piano bar, but my husband claims he loves them. Is this a good one? We were planning on arriving at Jellyrolls at 7:30 on a Sunday night (I'm guessing they're open every day of the week...?). Would it be dead at that time? How long should we plan on being there? Although I've been to WDW numerous times, I've never been to the Boardwalk. What else should we do there? TIA
