Has EZY ever considered Ostend as a destination ?
From the UK anywhere north of Brum would be a good short hop. Ostend in itself isn't a bad summer destination, but it has good rail connections to the rest of Europe.
Whilst our southern friends can enjoy a ferry or tunnel hop over the channel, from MAN, NCL or GLA nipping over the channel isn't so easy.
I have travelled with Laker (1-11) MAN-Ostend, but that was in 1975 :-) & took only 45 minutes.
A cheap quick link over the channel is what many northerners would like. In fact, I'm surprised RYR hasn't bagged this one.
