I might be skipping the burger unless it's veggie lol, but I appreciate the suggestions!
Also, I know this isn't a skiing forum, but if anyone has some expertise ... my dad has really old skis, they are super long (I guess that's how they used to size them) but pretty narrow (definitely not powder skis). Will he be fine with them or is it worth looking into rentals? Planning one backcountry day, but it's with a guide since we don't know the area, and they supply skis. Other than that we will just be at the actual resort hills.
