My family is taking our first DW trip this December for 9 days and have questions about packing. Due to the fact that the weather is so unpredictable in December, I think it will be necessary to pack warm and cold clothes, layers etc. Do you pack 9+ outfits for everyone? DO laundry while there (is there laundry)? Check suitcases but then **** some items? What is your plan for a family of 5 for 9+ days?
