Went to BR in January on a charter out of DSM. Loved it. Liked the slot selection and good table games, only thing missing was bubble craps which is the only game my wife and I enjoy playing together.
Only passed by the non-smoking room, maybe saw 1 or 2 people head the way the whole trip. HL room is nice, lounge seating area and room in the back with breakfast/night appetizers. Guy first night hit $10k jackpot on a $10 Top dollar machine.
My advice is if you have Freeplay on your Beau Rivage offer is to bring it with you and head over to Hard Rock they will match the Freeplay if you haven't had a card there or are inactive for a year+. We were able to double up on our freeplay as they matched the $600 from Beau!!!
