LE Diet and Travel

Hi Atomic,
Turns out that my husband has to be away in Phoenix, all of next week (the time when I'm ovulating). So, I'm going with him, and we will be TTC.
It sort of sucks that the week of Ovulation and part of 2WW, I will be stuck in a hotel, and unable to carry on my diet the way I want to.
I've been pretty good with diet so far.
What are some things I can do to keep up the diet? The thought of calorie loaded, greasy and salty 'restaurant' food, scares me.
I figured I can go to a supermarket and stock up on fruits and almond milk to substitute a meal each day.
Thanks
