Question for the MGM Property Vets on the board, do rates usually fluctuate? I am ready to pull the trigger at MaBay or Signature and have noticed rates for both are lower than last week. Wondering if I should just book or is there a chance the rates will go even lower. Also, how convenient is it to cancel/rebook? I do the cancel/rebook dance with Dollar with every reservation, so I don't mind it! Thanks in advance!
