Hi Michele,
Welcome to the Disney Parks Moms Panel! You are a brave soul and your valor will be richly reward with lots of smiles and giggles from those little ones! Your trip is sure to be filled with laughter.
Yes, you can certainly bring bottled water and snacks into the parks. Feel free to review the
Park Rules prior to your visit. My family always brings bottled water and snacks into the parks. Even with purchasing a
Dining Plan, we need to refuel during the day.
With four little ones, you may want to make use of the
Baby Care Centers in the parks. Although you may not need a stroller, know that
Stroller Rentals are available. And, do check out the
Planning for Pre-School Kids and Little Ones Guide.
When our girls were younger, we had to return to the resort for naptime in the afternoon. Although it was hard to leave the parks in the middle of the day because we wanted to play forever, they needed a nap! Once back at the resort, we all napped then went out to dinner or back to the parks later!
I wish you the best as you plan.
