Best hotel and bar near River Center

I've never booked a room in BR because I live 30 minutes away but I'm planning to surprise my wife with tickets to a concert she wants to go to at the River Center. I want to get a nice room within safe walking distance so we can drink and not worry about driving. It looks like the 3 options near there are the Hilton, Hotel Indigo and The Watermark. Which one should I go with? Looking for one as nice as possible, not just simply a place to crash. Also, a plus if there's a bar within walking distance between the River Center and the hotel we can stop at after the concert for a while. We're in our late 40's so something for an older crowd or maybe even if the hotel itself had a bar that was open late.

2 most important factors:

1. I'm not trying to get shot on this late night walk

2. I've been married for 29 years so all of this is an attempt to get laid with a possible BJ somewhere in the mix, so hook an old married baw up. LOL
