I personally have stayed at the Town and Country at least six times, probably more and always have had a great experience. While in past stays some of the rooms were a bit dated, I never experienced any issues with dirty rooms or pests. All of the rooms in the two hotel towers (representing the vast majority of rooms) were renovated two years ago, so should be in good condition.
In addition to holding the AHA Conference at the Town and Country previously, the Brewers Association has hosted the Craft Brewers Conference there three times--I'm sure the CBC would return if it could still fit there. We've had great service from the staff at the Town and Country for our events, and they love our attendees.
As has been mentioned in this thread, the Town and Country is in San Diego's Hotel Circle. Once the Town and Country fills up (and it will), we will be releasing overflow hotel info with group rates for the AHA Conference at surrounding hotels. We'll also have shuttles running from overflow hotels to the Town and Country.
I am quite certain everyone attending this years conference will have a great experience. I know I can't wait to be back in San Diego.
See you there!
