Congrats on the weight loss and YAY for a Disney trip!
My husband and I recently went to WDW; I have a gluten intolerance, and despite the amazing allergy service with Disney, we preferred to pack our own healthier (cheaper!) snacks as well. We saw some healthier snacks for sale in the parks, but for the prices they were asking, we were easily able to pack it in our backpacks for much less money.
We used a camelbak-type backpack with a freezeable gel insert that held about 2L of water. We put the insert in the fridge overnight, filled it with ice in the morning, and put some of the veggies that would benefit from staying cool (carrots, the cheese, etc) next to the gel insert. It was well inside the backpack, so it actually stayed cold - not cool but cold - for a good while. The ice melted slowly, so we could refill the insert at a water fountain during the day. We also carried little 16 oz Nalgenes that fit easily in my backpack.
We also like to split entrees, there was no issue at all when we asked.
For a fun treat, the Dole Whips are pretty lo-cal (and gluten free!), and they're REALLY good
You can get them at Aloha Isle in MK or at the Polynesian somewhere, I believe.
Wow! Everyone thank you so much for do many responses , tips and well wishes!! These are all great tips! I had never heard of a backpack with a bladder and will get one for sure. There's no way my husband would pay 100 for a meal and never more than once. I will look at the menus and plan carefully. Thank you so much!!
