at 7 months I'd just skip food while I was at disney. Most are eating very little at that age.
We didn't need to worry about food for DS until he was nearly a year. Made things so much easier! Since you aren't giving him foods yet, I'd just wait longer for it.
Also, as nice as homemade baby food is (compared to commercial stuff), I've always felt that you're setting yourself up for troubles in the future, by making *different* foods than what you're eating. If your'e nursing, baby is getting light flavors of the foods you're eating through the milk. He's getting primed to live in your household. To feed different foods confuses that. Then he gets used to *that*, and then later you switch toddler to the food on your table, and it can get confusing again at that time.
My mom, who started solids just WAY too stinkin' early (as did DH's mom, and we have the food sensitivities that tend to go along with that), had a good idea in the Happy Baby Food Grinder, which just sits on the table. Put your food in the hopper, turn the handle, out comes mush that tastes like what your'e eating. No confusion. My MIL, who was questionable at parenting in many ways, did about the same. She's Korean and uses Korean spices, but she would dunk the food in water, to take the heaviest spices off the food, mush it up and give it to her babies/toddlers. Same food, no problems with different food flavors/tastes in the future!
Not that you asked for all of that, but hopefully it's helpful. My mom always gave those food grinders at showers, because they were SO easy. Now they are called KidCo, but they are the same thing. I actually bought one before I realized that I wouldn't be feeding my little dude food until he could really EAT it (except for one "grindered" banana when I lost my mind, LOL), and it still sits here, waiting for me to get it to someone else. (but I keep telling people about my experience and no one wants it after that, silly me!)
Anyway, if you're going to do the mushy-food thing, it's really a good piece of equipment.
