Oh lucky you! I love that place! I don't really know what to suggest except to be sure to have a large enough budget. Not saying that about the admission, but rather the shopping... every country represented has stores and gift shops as well as a few restaurants. Next time I want to try chocolate from each country. Online research will help you to know what you want so you can save some time while there... I had a silk kimono robe from Japan chosen before arriving or it would have taken forever to decide.
Each country has a full service restaurant and at least one smaller restaurant. Love the Morocco cafe... I'm not sure if all the restaurants and shops survived the pandemic... haven't been there for a few years now.
