Lenders bagels in the room
We bought a pile of Lenders bagels at the nearby Winn Dixie,which made a huge difference for breakfast and they don't seem to go stale.:lookaroun
For bringing food into the park, Tuna in a pouch is great for that protein to keep you going, fills you up, and travels very well but buy it at a home supermarket.
We stayed at Pop as well. I got up early (6-6:30) every morning and filled my refillable mug once, drank it down, then filled it again to do me for the morning.
I brought my empty mug into the parks with me so it was handy (and light) for the trip coming off the bus back to the room and then filled it usually once or twice more before turning in for the night. I certainly got my moneys worth, plus I have a great souvineer with fond memories of my times walking around Pop, watching people arrive and leave while I was staying.
Do we know if the OP is driving? I think we've wondered but haven't heard,yet.
