Marc,
If its not too late to respond to this, I lived in Breckenridge for a while. Great place! It's been a while so I won't even try and reccomend any places to eat. To give you an idea of how long it's been, I was on the crew that put in the high-speed chair on peak 8. (over 20 years ago)
I do caution everyone that it is very easy to get dehydrated at that altitude. If you have a chance, spend one night in Denver before you head up the mountain. It will help get everyone used to the altitude. If you can't do that, be sure to drink lots of water (not just juice) and very little or no soda! Try and take it easy on the first day up there. Do some looking around town and shopping. It will help you get used to the elevation. If anyone gets a bad headache or starts to get congestion in their lungs that is not associated with a pre-existing cold, seek medical attention. It doesn't happen often, but a few people have serious, potentially life threatening reactions to big changes in altitude. I was on the volunteer fire department as a First Responder there and we saw a few such cases.
You most likely won't have any trouble, and everyone will have a grand time! Just keep everyone drinking lots of water and watch out for headaches or sudden chest congestion.
Feel free to PM or email me if you'd like more information.
Again, don't worry too much, and enjoy the place. It's one of my favorite places in the whole world!
Also, if you have the chance Tiger Run tours gives great snowmobile tours just East of Breckenridge. I was a tour guide there for a while and it was a real blast! Everyone gets to ride their own machine and you get to open it up out on the trail a couple of times! You'll get a great view of the ski area from across the valley and you'll see a lot of old mining buildings and get some great history on the area. Highly recommended.
