UK - Denmark fares

The Link.

It appears that, as of this year, ferries depart from Harwich at 6pm and arrive the next day on Denmark's western coast at noon. The fare's 34 GBP through June; from July 1 on, it's 59. (Let's leave the UK before July, yes?) And if we want to sleep in a bed that night, 2-person inside cabins are 14 GBP a piece.

I'm still looking to see if there's anything cheaper!
