Update: Deal is dead. Someone called Hyatt to ask about it, which alerted them so they pulled the offer. The rule is: If you see a great rate book it, never phone in to ask about it.
The Hyatt Regency Paris Etoile has a possibly-mistake rate which is bookable now for stays until next summer. This is an unbelievably low cost for this quality hotel near the center of the City of Lights.
I’ve made a personal reservation a few minutes ago for 3 nights in July 2017. They are showing as cancellable until 4 PM the day before. Some commenters believe this is just payment for an upgrade, not an actual room…I hope for clarification in the next few days as people begin arriving for their upcoming stays.
