It's hit or miss. I was looking for CG. I would put in my date, then advance the calendar for each of the next 4 days. All of a sudden all these CG reservations were opening up on several different days. People cancel and rebook all the time so just look when you think of it. I have gotten things at all times of the day so don't just look in the morning. btw I usually put in a time, rather than breakfast, lunch or dinner. Because: sometimes you can put in lunch for a place like Tusker House, and nothing comes up. But if you put in a time instead, like 12pm, you will get times that are 2 hours before or after. So you may get an 10:50am opening which is technically breakfast, but they start serving lunch at 11am so you will essentially be there for lunch anyway.
