Unfortunately, Shirl, you're rather limited for choice when it comes to accomodation in Greenock. There's really only 3 hotels and a couple of B&Bs. If you widen your search to include Gourock you might get a few more. There are plenty of bus services operating to get you around and the views are pretty spectacular.

Also, with Slanj being a pub rather than a club, we'll have to get all the equipment out after the gig, so there will be a couple of folk staying sober enough to drive, so you should be able to cadge a lift... wink
