I've just booked 4 tickets for £11 each this afternoon for the upcoming Disney On Ice Princess Wishes tour at the Liverpool Echo Arena on Friday 27/11/09. Merseyrail are offering a special discount of £4.50 on the normal £15.50 priced tickets, for the Friday show, making them just £11.
These are really good seats located at the front of the arena. You don't necessarily have to be a Merseyrail "customer" you just need to quote the word "Merseyrail" when booking the tickets. You can also avoid the booking fees like I did by paying cash at the box office.
The ad for the discunt can be seen at Merseyrail stations, including Lime Street underground. (limited 4 tickets per person)
