Seem to recall the missus and I had a similar lengthy connection last time when flying in F from T5. I was expecting a howl of protest from her so suggested we leave and go somewhere.But no, she was happy to stay put so we dd. The time flew by and that was without taking advantage of all the facilities on offer. To be honest we both rather enjoyed doing sod all. Plus we didn't overindulge on the food and drink on offer either.
