Longer trips happen all the time. Our outfits have been to many places in the western world and also around the world on cruise ships.
Our normal rental is for the weekend with pickup on Friday, let's say, and bringing back Sunday or Monday. If you need an extra day at this point we are inclined to allow it, but you must tell us about it or late fees will apply. If you are out a whole week, the normal rate is an additional 50% of the rental fee.
However, this may not apply during the last two weeks of October for certain very popular outfits.
Also note this additional fee is less than the late fee (which we have been forced to raise due to the human condition) which brings us to the next question and yes, further negotiations are possible.
