Breakfast is pretty easy. We usually just have the hotel's breakfast. The key here is take extra's back to your room. Sometimes we would eat in the lobby then make a plate for later. Others I would go down while kids were sleeping, then bring up food for them. Even after doing that I would bring them down after they woke up for breakfast. Why? The extra food taken to our room was usually used for a snack or even lunch.
This is when I would eat leftover breakfast foods. We would use the bread meant for toast, with the peanut butter and jelly packets make great sandwhich's. Or sometimes I would pour cereal in a bowl and milk in a cup for a snack or lunch later. Yogurts and fruit were easy to store in our mini fridge. Oatmeal and hot chocolate packets easily cooked in a micorwave or with the coffee pot. Bagels and extra cream cheese packets were one of Kadan's favorites. I also used the coffee pot for cup of noodles. Then we would go out for kid's meals once or twice a week.
Dinner was a little trickier. Especially when trying to avoid pizza, fast food and spending lots of money. I used my plug in griddle a lot. With the griddle I would have lots of grilled cheese's sandwhich's usually with stolen left over continental breakfast bread too! Quesidilla's were really easy as well as grilled tuna sandwhichs. Sometimes I would grill the roast beef with some cheese and brown some cut french bread for a hot sandwhch option. If you buy those add water and easy pour pancake mix containers and can steal small syrup packets as well this was another cheap yummy dinner most kids love. Sometimes I would eat heated up chilli and micorwaved potatoes and a salad. Those meals and a dinner out to eat 1-2 times a week we were pretty much set.
Just make sure to have paper products, plastic utinsils, paper towels, baggies, a spatualla, can opener 1 or 2 tupperware conatiners for mixing or storing, and no spill cups are great.
