3. Pour coins into your hotel sink
Sometimes you need to wash your clothes a quick wash but there is no washing machine in the hotel room. Try to place the plastic bag on the plugola and weigh it with coins. This will create a blockage so that you can wash the cloth in the sink.
4. Use compression bags
To pack more and more items, you can use compression bags. Suck the air from the bag with a vacuum so that you can add more storage to your suitcase.
