You're not eating right
I think a problem is that you're not eating right.
Start off with a decent breakfast, ie eggs overhard (something that's easy on the oil and butter) with a little bit of cheese if need be, but often times the restaurants just put too much on. A complex carb such as oatmeal would be fantastic (take it easy on the sugar, none would be ideal as the GI on that is high). Have a piece of fruit too. Personally, I would avoid the hash browns as that stuff will make you FULL and put you to sleep. If you're going to have toast, try to have 100% whole wheat ... just avoid anything with refined/enriched carbs as that stuff will put you to sleep too.
Then mid morning eat something like a banana and some beef jerky.
For lunch, you can have a sandwich, but again, I stress avoid the processed carbs ... stick to the 100% whole wheat breads. The grittier the bread, the better for you. If the bread almost melts in your mouth or can be easily "mushed", that's the stuff that puts you to sleep. Lodgefoodwise, try to eat a healthy sandwich or a salad w/ some protein and good veggies ... ask for the dressing on the side and only use a little bit of cheese if necessary. If you're going to eat some fries, share them with friends.
In the afternoon, have a protein bar ... problem is with those is that they're chock full of chemicals, so try to only have one a day. Be sure to mix vegetables throughout the day too in your meals!
When calling it a day, eat some protein and carbs again, as your muscles will need the nutrition to recover. Banana, jerky, and some carrots would be great.
Then for dinner, don't go crazy overboard with a 2000 cal meal ... perhaps it's something you can do 1-2x a week. I know you're on vacation, but if you do that every night, you'll probably start feeling like crap and you're energy level won't be as high, which means you're not going to ski as well as you could. If you don't care about your ski performance, then eat away!
1) Eat a fairly balanced meal every 2-3 hours (ie low-fat protein, complex carbs, and a lil' bit of good fats)
2) Eat complex carbs and avoid the sleepy refined/enriched/starchy carbs
3) Eat veggies and STAY HYDRATED (all jackets should have camelbaks as standard)
4) A little bit of caffeine can be consumed ... perhaps a cup of joe in the morning and a cup after lunch ... although lodge coffee usually sucks and costs $3 a cup.

The newer answer for optimum performance for all athletes in longer term (more than 2-3 hour) athletic events is:
1) a good breakfast involving lean protein, fruit and fresh veg at least an hour or two before you start skiing; and
2) lots of small meals/snacks including complex carbs and electrolytes (sports drinks and juices, fruit and dried fruit) and lean protein (nuts and lean meat, tuna, salami, jerky, etc.) during the day. You need to start reloading complex carbs (fruits and veggies) within an hour or so after you start exercising for optimum performance.
3) a recovery drink including complex carbs (fruit juice, fruits) and protein (whey, egg white or similar) as soon as you finish exercising (lemon in the hefeweizen unfortunately does not count). You can actually buy a prepackaged protein drink with fruit juice in health food stores like Whole Foods if you don't want to premix you own, or I imagine a large OJ with some jerky or salami on the side could work in a pinch.
I think one of the reasons most people get tired after lunch is because they are dehydrated, by eating a meal you change the solid content of your body and unless you hydrate sufficiently you feel the effects more severely after a meal. On top of that you are usually fighting dehydration in skiing since this is exacerbated by cold and altitude. So stopping to drink often or using a hydration pack with sports drink or fruit juice, in addition to the above small meal strategy should work to alleviate the post lunch crash.
