I stayed at the Hyatt Place in Lombard, IL last week, and really liked it. The facility renovations were complete, the 42" plasma was connected to a full HD signal, and the whole experience was just as advertised.
Different story this week in San Antonio (Northeast)...LOTS of construction still going on, both in the lobby as well as the first-floor rooms. They can't even sell you a bottle of water here yet, and going out to get one isn't quick & easy, due to the hotel's location on a one-way access road that parallels I-10. The room layout is identical, however, and I'm finding I really like having such a big TV. (Unfortunately, no HD signal here...just regular lo-def cable.)
In short, I like the Hyatt Place concept, although the suite situation reminds me why I never stay at Embassys anymore while on business (too many noisy families). But it makes sense to be wary for a while as the hotels are being converted.
