If it's the same object and they were mapped as a node before and are remaining a node, it's best practice to move the node, not delete and recreate. This was done for most of the existing campsites that have been updated.

Thanks for confirming the source too. It's best to add that in when you edit, especially for something like this that can't be determined from aerial imagery, that way other mappers know that you've checked in person and it's not potentially from an undisclosed source online.
