How much extra $$ should I consider?

It's notorious that drying clothes seem to take forever... hanging them means give them 2 days likely not Overnite. If u use a dryer, clean the filter.
Enjoy ur trip!

It actually took us not even a day. Most were dry when we got back to the room after dinner.m and all by the next morning. We didn't have much clothes and they were all very light ones.
