Hi Olive:
Enjoy your stay at Saratoga Springs. My family has stayed there twice and has really enjoyed the atmosphere. You can arrange to have outside pizza or food delivered to your resort. Check with the front desk for some suggestions or check out fooddeliveryorlando.com for other food delivery options. Note, however, that the resort's counter service restaurant,
The Artist's Palette serving tasty sandwiches, flatbreads and entrees, is generally open from 7:00 a.m. to 11:00 p.m. If you arrive around 7:00 p.m., you should have plenty of time to pick up food at the resort if you prefer.
While we are talking about Saratoga Springs and food, also consider dining that the resort's sit-down restaurant,
The Turf Club Bar and Grill, during your stay. My family finds it to be an "undiscovered" gem of disney dining.
Enjoy your vacation.
