Take a gander at the size of Texas and Germany by visiting google maps and then consider how travel time from point to point can consume precious vacation days. Given her passion recommend emphasizing this is her first, but not last, trip to Germany.
First trip jitters are normal, but highly manageable; especially by using the resources of RS forum members.
A couple of tips on managing "jitters":
- pack less, far less, then makes you comfortable. Being a luggage mule is a real hazard to trip stress. Suggest limiting yourself to one carry on bag each and keep practicing on how to achieve this objective. Less luggage, less stress. Everything you think you need can be found in Germany.
- Less travel days from point to point equates to less travel stress and expense. Seven days will fly by and our experiences find absorption of your destination creates more wonderful memories than just seeing the destinations.
- Our daughters had to "earn" their way onto trips by actively participating in the planning. Their international travel started in middle school and they often comment on the travel skills developed by being "forced" to undertake the task. I suggest you direct daughter to start asking for help from the RS forum to learn similar travel skills. Ownership of trip planning offers an abundance of life lessons.
As for destination recommendations suggest your daughter be tasked with asking these questions of the forum. Try and be a bit specific with information requests, but flexible on the answers forum members travels may suggest. If planning this trip was an onion, keep peeling back the layers to learn more about how to make the best use of forum members counsel.
Keep in mind, forum members desire to help you achieve a wonderful journey!
