I actually work in the hotel industry, and the way that we would view this is that we would have an opportunity to sell that cancelled room at a much higher rack rate.
The advantage of seeing advance purchase rooms on the books is that it helps with forecasts and labor, but the revenue is much lower. Walk in customers push the ADR (Average Daily Rate) much higher, so like I said, "No big deal" Just remember to keep the cancel policy in mind, because we do charge!
