How Your Luggage Can Effect the Cost of your Travel.
Generally if you use a suitcase you are limited to where you will go, your best bet is airplane to taxi to hotel as they are not that easily portable, the problem is this.
The wheel system on the suitcases are generally quite heavy compared to a strait cloth bag, many wheel system bags are also hard, these two factors can make the bag difficult to carry. If you hit some rough terrain or a staircase or boat or buss es etc, the bag is so heavy it is just plain tiresome to do difficult traveling with.
You are therefore limited usually to traveling to destinations with other people that have heavy luggage, and share the same “convenience” priced hotels with all the others of your sort.
If you carry a backpack with the same items in it, you can usually travel a bit further because the weight preferably balanced on the middle of your upper back, the baggage itself is lighter, and you are in balance for walking up difficult terrain if you wish. Eventually the path will get to difficult or you are too tired, so you stop with others of your baggage toting kin. These hotels get less traffic are are usually quieter, and less expensive, often they are less spoiled than the easy to get to beaches.
If you carry a light backpack, you can arrive at the same original destination but travel further by foot. A cloth backpack with a week or more worth of clothing in it is actually quite light on its own.
The further you get from the easy to reach places the cheaper it gets, and generaly more beautiful also.
