In reply to Mike Conlon:
Many people are sea sick on the boat. This can affect a team...
If you want to climb once you arrive in the afternoon, I'd suggest picking your route/ crag carefully. Finding the routes / ab points can be time consuming.
That walk up the hill from the ferry with a pack can also be more than you anticipate - pack light!
Albacore and aesofoetida are reasonable routes, OK to find and close to the pub area for example. But you want an ab rope too, and to be the first there as its not a great place for multiple teams.
The stuff around the limekiln and south of the island can be a touch loose/ adventurous/ tidal for the first day. Choose wisely
However, if you're a first timer...... Maybe just getting your bearings would be an advantage?
Even finding the slide can be an issue, such an icon, and yet so tough to locate for many. Walk the west coast and then return via the central path(s) keep an eye on where the landmarks are. The central paths are so much better timewise if youre heading north a distance.
Have fun, K
