I run where2.bm, a website targeted primarily to local residents of
Bermuda but also attract a lot of traffic from overseas, mainly the
US.  I will be introducing a specific section targeted towards holiday
makers and would like to find an affilate program where I can offer
cruise deals to Bermuda through my site. Can I have a recommendation
of 5 such sites.

Here's a few affiliate programs to consider:
