I was previously trying to decide between Mirage and Monte Carlo. Eveveryone said Mirage. Went to book the next morning and rates had jumped 2 nights up $50 and the other 2 almost $100. Can' t go that route, so now back to square one. Bally's has a really good rate better than Monte Carlo but don't know much about pool at Bally's. Help! Need opinions on both the hotels. Thanks!
