Well, the point is I don't think they need to be renumbered, since they come from the templates, so they should have the same numbers in every vacation hood. I'm not talking about any lots I've added, just those that come with the base vacation hood. I thought of packaging them and putting them in the lot folder, but my lot catalog is way to big as it is, so I'd prefer to avoid having to do that.
ETA: Never mind -- I thought the game kept the sub-hood lots in their own folders, but it doesn't. They're all dumped into one 'Lots' folder. So I guess packaging and replacing is the only way to go. Damn, I thought i was on to something....
