I will be in town for a wedding and staying at the Cordova Inn. I will plan to bring Walker (3yo) back to the room at around 830 and put him to bed. Ideally the sitter will just be there for if he wakes up until 12am when I will come back. If he wakes up and needs me I can return but he is usually a deep sleeper once he falls asleep so it should be pretty easy (did this same arrangement for a wedding last month and it worked well).
Watch a 3 year old, who will hopefully be sleeping, for 4 hours at the Cordova Inn while I am at a wedding celebration.
