We loved Anytime Dining! We always asked to be seated with others and never had to wait. We ate between 7:00 and 8:00 every night.
If you and J want to eat alone there may be a wait. DH and I eat together all the time-we liked eating with others.
We never made reservations (kind of defeats the purpose, IMO!) and enjoyed meeting many new people!
I think you'll love Princess!
