This review is for the conference rooms and the layout of the hotel only. My conference here was in the weirdest spot. You wouldn't even know this was a conference room if it weren't for the signs that our coordinator put up to guide us to the spot. I had to actually walk away from the ballroom where the other rooms were, go outside past the patio, go up a flight of stairs, and then walk some more past the tennis and basketball court to get to the room. There wasn't even a restroom on that floor, we had to walk some distance down the stairs again to reach the one stall restroom next to the stairs on ground level.
The room itself was comfortable enough and I could hear the lecturers OK, but it was really chilly so I'm glad I brought a sweater. During break time, after looking at the exorbitant prices for food at the two restaurants here I went off site for lunch where I did discover a few nice spots for a quick and less inexpensive bite to eat less than a mile away (Slanted Rice and Modern Market).
Because of the weird layout I got lost here a lot. There were a lot of times when I entered the hotel that I went the complete opposite direction. A person from a different conference in the main conference rooms actually had to direct me to where my particular room was!
Parking was of course on the very opposite side of the hotel but I guess it did allow me to walk off whatever I ate for breakfast and lunch. Parking spots were plentiful and I had no problems finding a spot at any time.
Conference-wise, you don't really have a choice in where you go, but for my experience here at the DoubleTree it was just so-so.
