My sister and I are planning a backpacking trip to Europe for the summer of 2011 (62 days). We are planning to visit the UK (England and Wales), France, Spain, Italy, and Germany. At our time of travel, I will be 17 (turning 18 just after our trip ends) and my sister will turn 17 about a week into our trip. This will be the summer before our last year of high school. Neither of us have traveled anywhere without adults before, and we've never experienced a major (or even moderate) culture shock.
One of the first things we decided in the initial planning stages of our trip was that we won't be taking our cell phones, laptops, or any other electronics (excluding our digital cameras; gotta have pictures to show friends and family). We really don't think they are necessary, and the chances of them getting lost/broken/stolen are too high. We can buy phone cards to call home every so often. However, this means we won't have a phone on us if we happen to get into trouble and need help. Safety is one of our main concerns, given that we are two teenage girls and will be in unfamiliar places. Does anyone have any advice as to what safety precautions we can take?
We're planning to stay in hostels to stay within our budget, but most do not allow guests under 18 to stay in the dorms. So we will have to stay in private double rooms. I'm sure there are other obstacles we will encounter; if anyone knows of any and how to get around them/alternatives, it would be appreciated.
Next, we are looking for backpacks that comply with airline restrictions for carry-ons (we don't want to have any checked luggage), and have detachable day packs. If anyone knows where we can find something like this, that would be amazing.
Also, any other advice would be greatly appreciated. We're new to all of this and want to know exactly what we're getting into. Thanks in advance!
