Our family of 3 has travelled a lot over the past 10 years. I think part of it depends on where you go. Hotel rooms in Asia and Europe tend to me smaller and "true" triples (2 queen or 2 double beds) tend to be less available than they would be in the states. Whether it be
ABD, Thomson, or Trafalgar, we have typically ended up with a King size bed and a roll-away bed. A few years ago this was no big deal. However, our son is now about 6' 2", so roll-away beds don't really work for him anymore. Occasionally, we would get a room with 2 double beds, but that tends to be the exception. Again, this is our experience for Europe and Asia. US travel hasn't been a problem with getting 2 real beds. On our most recent trip to Vietnam, the Halong Bay cruise was 2 rooms which was nice. One of the reasons we are going to the Dolomites with Right Path Adventures next year is that we can get two rooms, so he can have his own bed.
