I have never been to DW, but on holidays I do laundry in the evening while kids are showering and we are getting organized for the next day - I don't stay in the laundryroom, so It pretty much does itself.
I just go back after 40 mins to move wash to dryer then go back to the room to get more stuff done. I've also done it while kids are playing in the pool ( same thing - going back and forth) or while dinner was cooking or waiting for pizza to arrive.
On my last trip to DL someone had folded all my clothes and left them on the dryer for me ( the dryer was running with their stuff) I had no problem with them moving my stuff out of the machine so they could get their stuff going, and was tickled to see it folded. Felt like I had a laundy fairy godmother.
I try and do it every 3 days on holiday - even though I pack WAY more than 3 days of clothes. I just dont want piles of stinky laundry laying around. If its clean it can be put away in the drawers or suitcase with other clean things.
I also do ALL Laundry on the last night. and just keep one backpack empty to put dirty jammies in in the AM. That means although I paid to wash clothes, I arrive home with all laundry done and it can be unpacked into closets and drawers when we get home. NO trying to catch up a Mountian on laundry your first few days home.
We just got home from 10 days holiday, and the day after we got home ( got in VERY late) my kids just rolled their suitcases into their rooms, put it all away and it was HEAVENLY.
The last night of a trip I am packing, organizing and such all night, so doing a few loads of wash is really no more work. Espcially since I can do several loads all at the same time in the hotel machines. Then it just gets quicly folded and added into suitcases with the other already clean clothes.
I save up laundry soap samples all year that can be ordered online as 'freebies' , I bring a few sheets of bounce from home in a baggie, and I save US quarters I find in my change ( I'm Canadian) throughout the year and that covers my laundry expenses on US vacations.
Sorry to be so long winded about somthing so mundane as laundry, but thelittlemermaid it really will make your life easier to squeeze a few loads of laundry into your trip!
