Just had a quick look at the stats, not much to shout about 153 visitors last month.
Bing webmaster tools said its appeared in 3,538 searches this last month.
I think I get the odd commission on lateroom buts I have another site hotelsmiltonkeynes.org.uk that could be sending the odd sale as well.
So I would just go by no to be safe. Im sure the domain has a PR1 still as well
