I would skip the Mirage (since they're renovating), and stay at the Flamingo. If you get a gold card, you can bypass the long registration line (probably about a 20-minute wait) and get a free upgrade to their spacious suite on the highest floor, which had a view (approximately ~600 square feet).
We paid $150 for this room, and it came with a king-size bed, and a queen-sized sofa bed. The redesign reminds me of the Standard Hotel in Los Angeles, where you would have a unique experience. For instance, the neon pink lighting in the bathroom. There's even a television embedded in the bathroom mirror, so if you want to take a bath while watching your favorite movie, you can do so here.
There were two flat screen televisions (rarely used) and an empty refrigerator for cake or BYOB (for college students on spring break). Prior to staying here, we stayed at the Mirage, and incurred a $40 charge just for opening and closing the fridge 5 times, and we didn't drink anything. We just used it to store our cake. Anyway, I really like how their rooms are catered for the youth, and how they thought very hard about who would stay there. I can visualize a bachelor party or spring break, f-u-n!
