Brought 12 people there for a conference and it was quite disappointing.
-lost one of our reservations and two had to bunk together for a night before it got sorted out
-hot water in the shower was on and off
-rooms not made until after 5:00PM in multiple occasions
-understaffed restaurant. Long line and 1.5 hrs for breakfast.
-not friendly staff: guessing poorly managed and understaffed
-wife lost her room key and it was a hassle to get her a new one, even though we checked in together.

Worst Hilton I've stayed at
