Hi Tommo.
Sounds like the clean up is a great idea. I wonder if you still need the GB at all? Is this for language or country? If you are doing country/language I would have a folder for each ie
domain/en/us/title-of-hotel
You can then geo-target these to country specific areas in GWMT as well - which would be helpful.
And definitely 301 them all - this is a must.
