We just returned from a wonderful two week trip with my family (me, my wife, and 16 and 13 yo sons). I haven't done a trip like this since I was in college 25 yrs ago and the RS website helped me tremendously in pulling this off. Here's a brief report aimed for those that want guidance on travelling with teenagers:
Itinerary: London (3 nights, Luna and Simone Hotel), Paris (4 nights, Hotel Lutece), Brugge (3 nights, Huis Koning, day trip to Ghent), Delft (2 nights, Bridges House), Amsterdam (2 nights, The Toren)
Budget: It's definitely not cheap to travel with older children. The key factor for us was finding "quad" rooms that were still in excellent locations. We did pay for two rooms in Paris and Brugge. In Brugge, we did a B&B which made 2 rooms more affordable. I reserved most of the Quad rooms nine months in advance. We used a "no exchange fees" credit card.
Hotel impressions: We loved all our accommodations--and we're picky! I really agree with RS that finding a quaint hotel in an excellent location is the way to go. The Luna/Simone had no A/C which may be a factor for some. The Toren was a "splurge" but they had a quad room available which made this a great option for us. My favorite was the Huis Koning B&B. Lyn does a great job and offered a different "treat" to eat every afternoon which was most appreciated after a long day of sightseeing.
Method of travel: We travelled by train. Bought the Eurostar as well as the Thaly's train from Paris to Brussels-->Brugge in advance. The others tickets we bought at the station on the day of travel. In the cities, we walked, took subways and taxis. Taxi rides for four were often the same cost as taking the subway.
Packing: We travelled fairly light although we did check two bags. I did not bring jeans on the trip which I feel now was a mistake. There were a few days I wanted to dress more casually and everyone was wearing them! We did laundry once on the trip in Brugge.
Teenagers: They loved this trip! We live in a small town outside of Athens, Georgia and this trip really opened their eyes to the world outside the South. I feel that travel is an important exposure for teenagers and I have no regrets about taking them along on this adventure.
Alcohol: My son was happy to inform us that drinking is allowed at age 16 in Europe. Since he was curious, we let him drink beer and wine with meals throughout our trip. We discussed the difference between drinking a glass with dinner and binging at parties.
Amsterdam: I was concerned about exposing our kids to legalized marijuana and prostitution. However, in the end, we let them see it all including the red light district. It was actually a positive I think, and led to some frank discussions about these subjects with both my boys. We loved Amsterdam.
Terrorism: We felt safe during the entire trip. Friends/family were constantly "worried" about us while we were in Europe and we had been warned not to go. I'm so glad we just kept travelling!! Of note, we saw very few Americans during our travels.
Thanks to all for the advice from this website and these forums! We had a great trip--one that I will remember forever.
