Convenient but vast, easy to take wrong turnings as signposting told you where you were, but not where to go. Even Reception was poorly signposted, as it was in Lobby A, but there was also Lobby B and possibly C. Took the long route to event because no signposting in hotel.
Housekeeping knocked on the door at 10.15 when checkout wasn't until 12 and I was having a lie-in. Overall disappointing.
