There is precendent for this at the Towers.I assume even if the planning lapsed as it was timed out, it would be pretty easy to get it waved through a second time now they've been given the nod once already. As long as there were no substantial changes to the plans.
Before they built the CBeebies Land Hotel, they had previously got permission for an additional wing of the Alton Towers Hotel on the same site, with roughly the same footprint. That lapsed and then eventually the slightly larger, souped-up full hotel in its place.
