Front desk is under-staffed and it can take a long time to get even a simple question answered if they are helping other people. The rooms do not have refrigerators or safes, although I was told those are going to be installed soon. Doubletree (and I think Hilton in general) uses half-size pillows that are completely inadequate. A couple of standard size pillows per person would be appreciated, preferably different firmness in each. The tiny pillows are also very soft.
Even though the hotel was completely booked, it was quiet. Lots of electrical outlets around the room. There is plenty of parking, and important to us this time, plenty of handicapped parking right in front of the hotel. The breakfast buffet had plenty of variety, including fresh cooked eggs, bacon, sausage, potatoes, waffles, cereals, pastries, fresh fruit, yogurt, granola, hot and cold cereals and more. And it is not too far from the Princeton campus (note that traffic on Route 1 can be brutal during rush hour, but you can take back roads out of the hotel and end up on Nassau Street within 10 minutes). We drove to campus, but the hotel has a shuttle that services the vicinity and they will gladly shuttle you over to campus. The staff was very attentive, polite and accommodating. And of course, there is the famous cookie! They were very generous with the cookies, and if you asked, they had bottled water at the front desk.
