Having now been both places since re-opening, I think I'd recommend Biloxi. Vegas wasnt worse, but not really better either. The one difference, for me, was that there are more fancy eating options available in Vegas currently, but most have abnormal hours and abbreviated menus. I was in Vegas on a holiday weekend and not so for Biloxi, but my entire stay in Vegas the pools were mobbed at both properties from opening until close, so they werent doable for me because I didnt want to be waiting in line to hit the pools at 8AM. Beau Rivage had plenty of pool space open when I was there. Also they have the beach. I still had an awesome time in Vegas, and dont regret going, but I made the comment on my way out that I'm not sure I want to go back until things change. Also I was meeting a honey who lives in LA so one of us had to travel far regardless. But Vegas costs me $1,000 in airfare and everything else is more expensive compared to Biloxi where I can drive in half a day and food and things are half the price of Vegas or less, and still has all the same slots and table games etc, and still has pretty nice rooms. I couldnt tell much difference between my two trips other than scenery and Vegas cost me exponentially more money.
