When did MGM/Mirage properties start instituting a 72 hour waiting period in between offers? When planning our trips to Las Vegas, my husband and I normally stay for 7 to 10 days and break up our trip between three MGM/Mirage properties based on offers we receive. This time around we're being told we have to wait 72 hours in between offers. As a result, they've lost our business for some of our trip. Several of the MGM/Mirage properties have told me that this has been their policy forever, but that the hotels/casinos just haven't strictly enforced it until recently. This is kind of a bummer! Luckily, my husband received a decent offer at Paris, so we're staying there our last two nights and booked a room at NYNY for our first two nights via a Facebook offer. In the middle, we'll be staying at the Mirage via a great MLife offer I received. However, we're missing out on a complimentary night at Mandalay Bay because we can't figure out a way to make it work with the 72 hour waiting period. Is there anyone else out there experiencing this problem?
