There are several reasons, but I need to pack 2 suitcases for my trip, one reason is I am extending it with 3 days in London on the way back. I might be able to get by with one but would have no room for souveniers, so should I bring the two and hope for the best, bring the two and see if I an leave one at the balmoral until we go back there at the end of the trip or try and squeeze everything in one suitcase. Just one other point of reference, I pack only what i know I need and on my last 5 trips I did not overpack and I wore everything I packed. Suggestions?
