I have stayed the the Hilton Guadalajara many times during the last 3-4 years. Generally I have had great experiences there. Rooms are clean, beds are comfortable, and a great expansive Breakfast buffet that is included in my corporate rate. But the last 2 times I have been there (most recently Jan'13), the AC in my room had problems such that I had to change rooms one time, and the AC had to be serviced another time. Seems like they need to be more proactive about maintenance. Carpets were pretty dingy this last time also. Hopefully I just had the bad luck of getting the only 2 rooms that had AC problems. Otherwise this is a great place.
