1. My family already had an extra toaster waiting for me (because they are super awesome!), but if there is no extra toaster where you are going, then use toaster bags. These have saved me numerous times at hotels!
2. Always, always, ALWAYS have an emergency snack with you! There have been times where I thought I'd be able to buy a snack, but couldn't find anything to eat! There are even "lunchable-like" snacks by Go Picnic!
3. Check the plane's peanut packages. Now I know this might sound silly, but I checked the ingredients once and there was malt in it. Malt does seem to hide in the strangest places ;).
4. Call ahead when you are going out to eat! My cousin and I made a few phone calls to see what was on the menus, and this allowed me to make up my mind on what I wanted to eat before I got there. (Sometimes it's hard to make decisions, because everything looks so good!)
5. If you are going to stay with either family or friends, talk to them about setting up a designated area for you to prepare your sandwiches (this avoids the dreaded cross-contamination.) When I visited my aunt, uncle, and cousins, they made sure I had an area with its own cutting board and toaster.
Honestly it was a breeze traveling and visiting my family in Texas! A special thanks to my Aunt Belinda, Uncle Morten, and cousins Therese, Marius, and Vibeke (it is always so much fun visiting them.)
Here's a bonus tip :) On the plane, I actually had a cooler with me where I stored snacks. This was a good idea, because my flight was delayed! In the cooler, I had almonds, chips, a sandwich, clementines, and some mints!
