Will the hotel have a small microwave, refrigerator and a coffee maker which will allow you to heat just water? If there is no microwave or small refrigerator may be you could rent one for the days you will be there. If there is a refrigerator you could get milk, string cheese, crab meat and turkey sticks. The milk could be used to make protein puddings. The coffee marker could be used to make protein high oatmeal, soups, and some of the other high protein packaged foods like Sloppy Joe, Chili mix etc that this site sales in their store. Also some high protein bars and chips would be good.
Nine months from now you will probably be at your goal and will be able to eat a variety of good food items. With all the dancing you will be doing whatever you eat I am sure will be worked off. Good luck during these next 9 months.
