Be careful...not all the sweets are covered by a snack credit. Just ask at the counter before you make your selection.
We like the Pepper Mkt. Our boys enjoy the kids selection, but it is normal kids selections like chicken and pizza.
I'm not sure how much research you've done. This CS is different from any other. You will be shown to a table and each person gets a card with squares on it. You then go to the different stations to order your food which will be freshly prepared. They stamp your card and you wait for your food to be ready. I would suggest each parent take a child and "window shop" the selections before making your choice. Then one parent can probably take the kids back to the table where your drinks should be waiting while the other parent waits for the food. You don't all have to order at the same station; just stay centrally located to keep an eye out for your food. When you finish your meal, head over to the bakery counter and get your dessert. You can even get it to go and take it back to your room. You can get all of your food to go and sit outside or back at your room. So, if you walk in and let everyone decide what they want, one of you can stay, order, and take it where the others are. It's not exactly room service, but it works.
