My husband and I stayed at the Hilton Frontenac for 3 nights while attending a conference. This is a very nice hotel with spacious rooms. There seems to be mutiple buildings to this hotel, we stayed in the main building. The staf were very helpful and our housekeeper was very nice and thoughtful. The concierge lounge was also very nice and inviting. There was free wlrelss internet in the lounge. The one complaint I will make is about the couple of hairs I found in the shower...not good. We will stay again if in this area.

I stayed for two nights on business. I had 3 complaints. First, the hotel seems to pipe through its air system a strong airfreshner. Second, and most disgusting, I had a stain on one of the bed skirts that clearly looked like it was male fluid. Third, in order to get in and out, I had to walk through the literature/meeting space of a religious organization.

On the brighter side, the conference space was very nice and the food in the hotel was excellent! Oh and the rooms were nice and quiet. So much so, that when I finally heard a faint noise in the hall after 2 days, I was surprised by it.

My wife and I stayed here two nights for a wedding and everything was fine. It can be a little confusing to get around, and the hotel is older but fine. Staff was very helpful and the location is great. I would stay here again.

We stayed for 3 nights in a "King Bed Deluxe Room". Thanks to other TripAdvisor reviwers, we requested (and got) an outside room with windows. There are inside rooms without windows - ick!

Pros -
1) Though an older facility, nicely kept up and mostly updated.
2) Large, clean, comfortable room.
3) Large, clean bathroom with big counter, double sinks (but see below re tub).
4) Quiet AC/heating.
5) Nice breakfast buffet with full/hot breakfast or cold-only choices (extra charge, of course).

Cons -
1) The large bathroom had a strange tub - small, shallow and in the corner. Fine for a shower; worthless for a bath (except for a 4 year old child). This arrangment may have been an exception. A friend's room on the same floor had a standard tub.
2) They charge $10/day for in-room internet service. Bizarre! We used the business center PC at night to get e-mail (though never could get the printer to work).
3) The place is big and getting around is cumbersome. Old elevators.
4) There are apparent problems with key cards (or the clerks who prep them). Our friend could not get in her room after a long trek through multiple halls, up elevator, etc. Housekeeper let her in. It took four (4!) calls to the desk to get someone up and replace the key cards. To their credit, they gave her 2 complimentary breakfast buffet passes for her trouble.
5) Another couple started to go into their room and heard people in there. Seems they were assigned an occupied room; they could have walked right in. So much for feeling secure in your own room. The desk clerk reassigned them to an upgraded room.
6) Windowless interior rooms need to be avoided (unless you don't care).

Would I recommend it to a friend? It depends. This hotel caters to groups. If my friend is a part of a group and gets a good/discounted rate, it is a decent place to stay. Otherwise, I would probably find a better option (preferably with breakfast and internet service included in the rate).
