You will have to ask if you can be seated together when you check in, but since you are there during the very busy Thanksgiving week when most restaurants are fully booked it will be harder. While the hosts/hostesses at the podium will do their best, there is no guarantee. You currently have 3 separate reservations for tables that fit the party sizes you booked so there will have to be a large 10 top or smaller tables adjacent to one another that become available at the same time. Expect to wait longer or to be told it isn't possible because it is Thanksgiving week in which case you might be seated at tables near each other or on opposite sides of the room.
If you want a better chance of being seated together keep checking online for a reservation of 9 or 10. At least that way the restaurant will know that you are a large party. Everyone, no matter how young, eating or not, needs to be included on the reservation because of fire code regulations so check for 9 first, then if nothing comes up try for 10. As long as at least one person shows up for the reservation, you will not be charged for the "missing" 10th person.
