If by "spring offers" you mean any offer from a property that includes March 21 or later, they could come out at any time. If you mean the MLife corporate offer that includes March 21 or later, that will be the "Winter Offer", it may not come out until the first week in February. If you mean the MLife corporate "Spring Offer", it probably won't come out until the first week in May. MLife's corporate offers are named for the season in which they are released, and usually cover the rest of that season and around half of the next. For example, the 2014 Fall Offer came out the first week in November, must be booked by Jan 31, and covers through March 12.
Had an MGM Grand Spring Buzz offer pop up in my MLife account today, book by 4/30, stay by 7/31. Mentions the same amount of resort credit as the Winter Buzz offer, but doesn't mention any free play, so I'm waiting for the email that usually shows up later.
Got an email yesterday with a "Spring Offer" from Aria. It looks just like the last offer titled "This is how we Vegas" but has new dates 2/1-4/30 Same offer as last time:3 nights SkySuites,resort credit,2 tix to Zarkana
I got my Aria offer too. 3 nights in a suite, $300 resort credit, $500 free play, 2 tickets to Zarkana. But I'm happy to report that Bellagio loves me again. I decided just for the heck of it to call to see if the spring offer was out and it was - good through June 30. 3 nights in a suite, $700 in free play, comp food and beverage, VIP check-in and limo. I know where I'm staying in May!
I have been very happy with Aria and my host.Always get SkySuite offers and RC. Unfortunately my upcoming NYE trip has been a debacle and I am pissed. I would consider trying Bellagio again but the host I dealt with there was such a jerk I can't stomach the thought of giving them business.
No, my experience with a Bellagio host wasn't warm and fuzzy either. I'm lucky that I get really good offers from them, so I don't even have a host there. I am just glad to be back on their "good" list as it is my favorite property. I think Aria as a property is nice, but I just can't seem to be able to win there.
