2 nights - depending upon the train connections, will either arrive in Hanover 9.30, or 10.30 Wed night, then booked in for Thursday night as well. Train on Friday morning is at 6.20, i think. Hotel is booked (Hotel Iberico, apparently in the red light district!), but not booked the trains yet.gone for it, going to book the same flight's as you then. see you in the lounge. are you stopping in hanover over night ?
Sounds a lot of messing about, but can't be worse than a 12 hour drive back from Lille on Friday
