I have a six hour stop over in YVR (flight gets in at 10:40 and I leave for a US bound flight at 18:00). I'll have to be back at YVR by about 16:00 to go through pre-clearance for my outgoing flight.

Is it worth going into the city? I was thinking Grenville Island or Robson Street (but could be convinced of other places). Or should I just stay at the airport (I do have access to the Maple Leaf Lounge, so it would be comfortable(ish).

The Fairmount doesn't seem to have any 'dayrooms' - which may not be worth it anyway.

Thanks
