Or Gatwick as I will be coming from work and as I work in lovely (?) Crawley, am right beside the airport and will have to pass it on my way. Only problem is I finish work at 2pm so might be a little early.
We did actually ask this when we visited as we know how traumatised everyone was at not being about to get into the Shop at G2G9, and we have been reassured that the shop has extended opening hours, and as it is just next door to the office (you can see into the shop from the office) they would even be happy to open it specially for us if there was no one serving at the time we want to go. (Well within reason....I think they might object to us banging on the door at midnight demanding badges!!)
