try billy nutt
nutt travel he always trys to give good deals for people travelling to and from road race events
let them know your going to the ulster gp rather than just booking a ferry but aslong as weather aint bad im sure you wouldnt regreat doing the southern 100 really is a good event and in many ways its actually more enjoyable week than the tt
nothing can be compared to the tt but the southern is that well run and more relaxed without people trying to rep you off (steam packet exclueded as they have upped the price big time over the last 3 years )
and great close racing aswell
