Of course, if it is a long trip – you can always buy the more important things like the sunscreen and shampoo from the place where you are travelling to!
Luggage is the most exciting thing. One tip – if possible, carry your lowers, t-shirts and under garments all in different laundry or packing bags. It creates less of a mess in your luggage!
Depending on the type of travel, I decide if I have to carry a duffel bag or a backpack or a trolley luggage.
