eKatherine has some great suggestions. Most fast food places offer salad now which is great, although generally the dressings are total crap. Maybe you can bring your own oil and vinegar and whip up your own dressing. That stuff doesn't need to be refrigerated, and you can make just enough for a serving.
I find it strange that the hotel you are staying at doesn't have fridges. I've worked in hotels for 7 years, at several different ones. Most offer kitchenettes rooms, and IF they don't have them ( like the one I work at now) every room always has a small fridge. I did actually come across one in Vancouver when there for a holiday that didn't have fridges BUT I called them and asked if they could provide one ( as with small kids I needed one) And the hotel had some that you could request and get put in your room. I would try calling the hotel you are booked at and ask them if that is an option. (might be an added cost, but if your boss is playing for the room, you can always ask to have that separate from the bill if she doesn't want to pay it)
Additionally, staff might have a fridge in their "staff room" that you may be able to store some of your food. Its a pain in the ass, yes. But I know I've never turned down a guests request to store stuff in my fridge if they didn't have enough room. The hotel in Vancouver also said btw, that I could store stuff in their fridge if I didn't want to pay the extra fee to get my own fridge put it. Just a thought. Try calling the hotel and see what they can do for you. If they aren't accommodating, they aren't a good hotel lol.
There will come a time, you'll see, with no more tears. And love will not break your heart, but dismiss your fears, get over your hill and see what you'll find there, with grace in your heart and flowers in your hair.
