If you want to take kids
If you want to take kids and they don't have email addresses it's a bit more fiddly, takes a lot more than 5 minutes and is a lot more annoying.I've just looked at the buying process to see what the fuss is about.
I created an account in Mrs Jeff's name. I added her to my "friends and family" list in my LCFC account. I added two tickets to my basket, and assigned one to her.
It was a bit fiddly, but easy enough to do, took less than 5 minutes.
