2.5 days to spend...

Hi!

Travelling to CPH on 10/7 and have to be in Paris to meet up with friends on 10/10.

I have a hotel room comped for 10/7 and 10/8 in CPH...question is do I stay in CPH for one more night and then fly to Paris?

Or do I leave CPH on 10/8 and head somewhere new or to Paris to be able to spend more time there?

I will already be in Paris from 10/10-10/14.

Thank you in advance!
