I booked through my long time TA on the first day bookings were available, and no mention was made of the slides or obstructions. I also notice that with the corners from the jutting out of the mid section that there may be a considerable lack of privacy on some Haven balconies. I am in 12300 on the transaltlantic, and will post real comments then. I will also ask for some compensation if it really is a problem, as I am pretty sure there will be not comparable suites to move to.
