Eating well while out of town
So I am going to Vegas this Saturday and will be there for 6 days. I will be in classes and conferences from 8-6ish everyday with no meals provided. There are several restaurants at the hotel and I'm sure other restaurants all around but I am worried about eating healthy while I'm there since I'm not sure how much time I will have for the hotel gym (other coworkers who have done this training say it's exhausting).
With no fridge in the hotel room, what would you recommend that I bring? I don't travel very often so I don't know what is ok to pack- can I bring fruit/veggies in my carry-on?
I know this is kind of a weird question but I just don't want to go way over my calories for an entire week. TIA
