About half an hour in advance, the staff of relevant positions will speak and send a map. There are some around the booth near the signature. You'd better buy it in advance. Ask your wife politely before signing, and most wives will agree, but don't sign when there are many people. You can prepare some small gifts, such as your own paintings and words. It's best not to bring anything edible. Now the circle is too messy, send something practical:)
