Excellent news, and I hope we're lucky enough to get the new seats on our next excursion to the in-laws.
I get the impression - and I'm voting in favour with my debit card - that EZ is trying to make the experience as pleasant as it can be within the cost constraints, unlike The Other Lot who seem hell-bent on making it as unpleasant as possible, in order to drive home the "it must be cheap" message.
As for the floor space comment - yes, that *is* one of the things you pay for.
