Hello Amy!
Welcome to the Disney Parks Moms Panel and thank you for the great question. Substituting table service credits for counter service meals is not something I'd recommend, based on the value of a table service credit. If you happen to have remaining credits at the end of your trip, it would be at the discretion of the counter service location to accept your table service credits. It seems you are arriving November 7th, is this correct? Running a quick
advance dining reservation search for tables of 4 on November 8th shows many options still available. Maintain open filters on your searches. In lieu of selecting exact times, try "breakfast," "lunch," or "dinner" as you search. Keep in mind the Deluxe resort hotels and Downtown Disney offer wonderful table service options.
I can certainly help navigate the site for you, so feel free to write me back with the number of guests in your travel party and the rough itinerary of which park you plan to visit on which day. If you'd prefer to speak to Disney Dining directly, you can give them a call at (407) 939-3463.
I look forward to hearing back from you, Amy!
