Welcome to the Disney Parks Moms Panel, Marie-France!
The
Disney's All-Star Sports Front Desk folks seem to be unable to connect to
End Zone Food Court Area. The Cast Member I recently spoke to said it might be better to ask in person once you arrive. They are all super friendly and would do anything in their power to accommodate guests' requests, so I do not think it would hurt to ask.
The last time I redeemed two quick-service entitlements for a whole pizza, I asked for some extra marinara sauce and was given such a big bowl I thought I'd be charged extra but I wasn't. Again, I think your best bet is to ask the Cast Member at the pizza place; in the event, they had to charge you, I do not think it would be too much.
I hope you find this answer helpful and enjoy your upcoming visit! Please come back with more questions if you need to.
See you real soon!
