At the Doubletree in Bristol, CT over the weekend. Two rooms booked. I have done this 5-6 times previously, with breakfast for 3 adults and two kids being fully comped due to Diamond. This most recent trip it was the $10 per adult credit- only allowable for one room. So the $80 bill was reduced to $60. Yes maybe the second room benefit should not be expected but this was an eye opener for me. There is a decent HS down the road that will get a closer look for future stays.
