A friend and I will be leaving for this trip out of Chicago O’Hare. This is a first trip with RS for both of us. Any advice from experienced RS travelers would be greatly appreciated. Food quality? Accommodations? Enough rest time? Any need for dress clothes? We’re planning on taking casual walking clothes and shoes, but do you dress for dinner? Also, to avoid delays/misplaced suitcases, we are opting to take a backpack and a carry-on roller case. It’s been a real challenge to limit ourselves to one quart-sized bag for liquids, etc. How does anyone do this without having checked luggage?
