I know, I know there is no comparison as far as rooms go and I've stayed at both before. I'm just having a really hard time deciding what to do for my first solo stay. I will be in Vegas 2 nights at the tail end of a LA trip. I currently have a comped Cosmo offer booked - terrace room no view with resort fees waived. I love the casino at Cosmo but am not really a fan of their pools. I noticed there are 2 comp nights through MyVegas available for Mirage on my dates. So why would I consider the switch? I love the pool area at Mirage and this would allow me to use some MyVegas rewards that require a stay (like freeplay). However, the main thing that is nagging at me is that I made it to MLIFE Gold level at the end of my trip last Sept and it will expire this year. This will be the only time I'll have a trip with this card level and I hate to waste it. I'd like to use the invited check in line once in my life LOL. Also, I have heard that you may get free upgrades with a Gold card? Just interested to see what I might get. Thoughts?
