Early signs quite positive.
Lovely architecture. Regenerated quayside. Street food, free entertainment, had a look around Hull Minster.
I know it's not quite a cathedral, but .. if we hear of any mysterious poisonings in Hull soon, we'll know Putins reach has extended to Spain
BTW since you are in the vicinity, why not take a trip to Bridlington, Filey and Flamborough Head? They're all a reasonable drive from Hull:
Filey is lovely and quaint, there's a nice little hotel on the sea front that serves good tea & coffee called Downcliffe House
Flamborough Head has the lighthouse, a cafe and some nice walking if the weather is good
Bridlington is a little dilapidated but we love it, if you go, call in to a hotel/bar called Rags in the harbour, the food is really fantastic and if you do end up there, say hi to Julie (the owner) from us! (She'll probably remember Brailsford, my surname - I know, poor OpSec giving out my full name on a forum..)
[edit] Could give you a million more places to visit, too..
