When we booked our upcoming cruise ( spur of the moment ) we were about 100 days out +/-.  Lucky to get a decent price & my choice of cabin, at what I consider last minute.   In the discussion with my new rep, he informed me that Norwegian was already over 50% sold out for 2016.  This was in December 2015.   Are you finding it more difficult to get the cabin you want, on the cruise you want, due to lack of availability ?  And do you find yourself booking your vacations earlier ?
