Coastal holiday - UK/Channel Islands?

Looking to book a coastal retreat (apartment, lodge or cottage etc) in July for my birthday. Somewhere different with the WOW factor. Possibly the Channel Islands or Isle Of Man.

Am I able to just hop on a ferry with Zeus? Is there anything I need to get filled in or a process I need to follow before I go?

Also, does anyone have any recommendations on coastal places to book?

Thanks in advance!

Here's a link for the IOM requirements http://www.pettravel.com/immigration/IsleofMan.cfm

There are no restrictions for the Channel Islands, however, you will need the pet passport and vaccinations if you then pop over to France.

Can't help with places to stay but interested in what you find
