If a group best to get Ferry Booking when they open up for 2018 bookings next month.I usually go Wed of Practise week for 7 nights, driven by Work etc, but if you are coming all that way, ideally you should try to get all of Race week and the Senior race. Accom is always tricky, use 'Visit Isle Of Man' link that was sent in the above message, it gives contact details of Hotels and B&B options and also Homestay and you should search this Forum, as a lot of useful info hidden away on Ferry Accom and Course hints and Suggestions. If you do get there, remember Ride on the Left....Eh! Cheers Azman.
