DD took on the research for our first European tour, since it was her high school graduation gift (a year later, but that's another story! lol) She knew she wanted to see London and Paris, and knew our time frame (she had just finished her first year of college and was able to travel in late May/early June). We were Disney people, but had never heard of
ABD. Their itinerary matched everything she wanted to see, so we booked it. We've since been on two more Adventures and are planning next year's Adventure!
The price is steep, especially for us as a family of three adults, but we've found it worth it. I am usually the one who is responsible for planning EVERYTHING, and I love how I don't have to on ABD. I just look into what we think we want to see on our own time, but unless it is a MUST, we also leave things open in case the guides have a better suggestion. I love that the hotels are first class, the luggage is carried for us, our transfers are handled, etc.
The "difference" is the bit of Disney magic that seems to be present the entire trip. Most of the other travelers have some sort of emotional connection to "Disney", whatever that might be. It sort of connects all of us before we "know" each other, and tends to cement some lovely relationships. We've kept in touch with a number of fellow travelers - friends from two different tours even came from out of state for DD's college graduation! Others we keep in touch with through Facebook and email.
On the flip side, DH and I had gone to a presentation by Trafalgar, sponsored by
AAA, and we were by far the youngest ones in the room. I couldn't imagine traveling for a week or more with people all much older than us. So far we've been on multi-age trips - from 6 years to 70's. We are looking at an Adult-Exclusive for our next trip. I personally would prefer a range of ages - it's fun to experience a far away spot while seeing it through the eyes of different ages.
The other thing we love about ABD is the special surprises that pop up during each trip. Whether it's going to the head of the line at a crowded attraction, an after hour tour, a private visit to a spot not opened to the general public... these things really add to the experience.
Only you can decide what is important to you, and what you are willing to pay for, etc. For us, we are very happy we've found
Adventures by Disney! Happy traveling!
