Don't know if you ever made your trip, but here is some useful information for getting around Belfast. Enjoy!(Go to Nileguide.com for more info - See links below.)

Hop-on-Hop-off Open Air Tour Bus:
You can hop-on and off as many times as you like aboard this open-top double-decker bus. There are 16 stops and the entire route takes approximately 1 hour. The bus departs every 15 - 60 minutes from each stop. Tickets are valid for 24 hours from first use.

You can see the Wall Murals in Falls Road and Crumlin Road, and the Botanic Gardens, City Hall, Albert Clock plus much more. With great views from the top of the bus, strategically placed stops and an interesting commentary, this truly is the best way to see the sights of Belfast.
