CalMac are introducing a new ticketing system this weekend, requiring changes to their website. You will be unable to make bookings between 0400 (4am) on Saturday 13 May and sometime on the morning of Tuesday 16 May- UK times.
This will include booking at ports.
On turn up and go routes you will still be able to buy tickets at ports as normal.
Anyone intending to travel on bookable routes on 13 to 16 May needs to book before 4am on 13 May.
Anyone traveling after 16 May will receive an e mail from CalMac with their new e-tickets.
After 16 May turn up and go routes will also have the option of being able to pre-book, but will also remain as turn up and go.
