Telly,
Most of the grocery stores that we like to take our guests to would be closed at 10pm. However, if you are ok with what you can find at a convenient store such as walgreen and others that might be open past 10pm, we would be glad to stop for you.
Regarding your reservation, while we can do everything we can to accommodate you with as short of a notice as that of a day, if you choose to book with us, we would certainly appreciate a little more than a day. I'm not sure if you would want a van or town car, either way we will charge you $70.00 for the round trip. and we'll pay the gate fee of $9.00 at the Magic Kingdom entrance.
Thank you,
Andy
