It’s maybe an unpopular opinion but if I came back and only had one day I’d do DL. DS is so spread out it’s really impossible to cover in one day. If you’re a big Disney parks fan DL feels more familiar/nostalgic but almost everything is just better. It’s like taking the US parks but removing rude guests, everything is cleaner, the rides are well maintained, and CMs are incredibly enthusiastic. There are so many rides in a more compact space that it’s easy to do things back to back without having to walk far. It’s less overwhelming in size/scope too, which is good for a one day visit.
