My husband and I are interested in seeing The Dan Band at the House of Blues at Mandalay Bay on April 6th. This would be the first time we ever saw a concert at the House of Blues. What can we expect? How big is the venue? Should we buy tickets well in advance or are we safe waiting till closer to the event date? Is the dining area completely separate from the stage portion? Would it be easiest and best to eat dinner at the House of Blues if you're already seeing a concert there? Any info would be greatly appreciated. Thank you!
