Yes, there's usually no problem going, it's the return i pay for really. I paid £40 altogether to Mytravel for this. I rang mytravel to do pay it over the phone, said it was because i needed to be away from the wing, she said we would have same seats going out and returning (window and middle seat at front). On return flight we queued for ages at corfu airport and were allocated two aisle seats right on the wing! We took them and I said to billy i would complain on return to britain to mytravel. I was shakin thinking of the flight home. We were sat in lounge waiting for departure when our names were called out over tannoy to return to check-in, we both looked at each other, like oh god that's us, one security guy was lookin at us very suspiciously, anyway it turned out the check-in girl had wrongly allocated us and we were given the seats I had prebooked. So i do think it's worth it for the return flight.
