This seems hopelessly complicated, the way I've imagined importing this kind of data (haven't done it myself) and keeping it up to date is as you say, keeping the node Id / way Id in a local table together with the version. If the version has changed the next time you want to update, you leave this hotel out and never touch it again with your automated scripts. The changed version means that the community has picked up the maintenance of this place and you don't need to bother anymore.
