I brought the sample packages I received in the mail home. Go to Tide.com or Google your favorite brand and they will send you samples. Each sample did 1 load and didn't cost me anything. Pack dryer sheets and the sample detergent in Ziploc bags in your luggage Purex brand has new 3 in 1 detergent sheet & dryer sheet combined. Also make sure to bring extra quarters with you on your trip, as the change machine at the resort was always broken and some guest even lost money in the vending machines trying to make change for washers.
