i think it would be a really good idea to be able to trade or give an item to another player. that way we could exchange plushies, foods, wands etc. we could even give gifts for a certain celebration (birthday, christmas).
another idea is tours. it would be really nice to have tours like in real life. of course you would have to pay for them. the workers giving the tours could show us around. rides,shops,restaurants and even some secret places. it would totally be an amazing experience for everyone.
