How can I treat myself to food on vacation but not ruin all my progress so far?

I’ve almost lost 10 pounds now and my vacation is in 2 weeks. I know I’m not going to lose that much more weight in 2 weeks, but I do want to treat myself to foods I haven’t eaten in a longtime since I started my diet and working out. There’s an exercise room in our resort that I could use every night, but I probably won’t have a lot of time to use it except maybe before bed. How can I treat myself on this vacation without ruining my progress so far? I’m not going to go completely off my diet, but I do want to splurge a little bit and treat myself to something not so healthy..
