I love HR Coconut Pointe. It's a great value, nice hotel, they just put in a new pool complex. Plus they have a ferry to a private-ish island. They have an above-average lounge. And, if you have TSU it's a a really nice suite (1 bedroom + 1 living room).
Late february and into Spring Break time, this is easily $400/nt.

HR Paris Etoile has completely transformed from a dump to a nice hotel. It's in a very convenient location for accessing metro (you can access without going outside). It's outside, and all downhill from Etoile to Arc de Triomphe down to the Champs-Elysees. The base rooms are small, but well designed. And also a very generous lounge.
Mid-June, these rooms are $400+/nt.

Hyatt Olive 8 (Seattle). Very nice, new-ish hotel. Great location in Seattle, walkable to everywhere. No lounge, but a FANTASTIC breakfast for Globalist.
Random day in June is $450+. And once you add in parking, easily $500+

Grand Hyatt Denver. I like the hotel. It's not amazing, but it's got a very solid lounge, and I've had very good success being upgraded. Very good location in downtown Denver.
Random day in July is $300+. It's actually only a Category 3!

Hyatt Regency Chicago. It isn't a great hotel, BUT it is a great location on the river in downtown Chicago. I love staying downtown to go to the Air & Water show (mid-August). Don't have to deal with driving/traffic, just walk to the lake front.
Typically runs $250. Plus parking (normally $70) is free.
