It was a pretty good hotel. Yes, the acoustics were awful in the PFS room where I spent the majority of the weekend, but it was serviceable, at least to me as a player. I was always at an outer table which may have help some as I was not surrounded on all sides.
The thing that got me was the internet issue. $14.95 per 24 hours of internet for one device only, what a joke, if you ask me. This is the first hotel that I have stayed at that has this big of a restriction and this high of a price. Granted I don't travel a whole lot, but I have been in my share of hotels and have not heard of this.
It is not turning me off of attending again next year, they are really minor niggles to me for the most part. I really enjoyed my first Paizo Con, and can't wait for next years!
