Good to know about Hyatt's properties.....sounds like I should save those points for other trips. Thank you.

I am a Club Carlson CC holder (and so is my wife). I'm very much looking forward to the last-night free option, if we do go that route. It looked like there were a lot of them in London/Dublin. I've never stayed at a Radisson Blu before though. When you book online, does it automatically remove the third night "cost" before submitting the form? Or does that happen afterward?

And yeah, hoping to book this weekend. My wife has been getting very worried about availability. 500+ Euro a night....yikes! Definitely don't want to get hit with that charge if I can avoid! I've been pulling open the hotel details on all sorts of tabs in Chrome.....trying to look at them, read reviews, compare. Thank you all for sharing some advice!!
