For me (but maybe not for the original poster), the K-x plus tiny DAltd primes I used last summer was the best solution ever. The size and weight complement each other, and I get a good slice of the best of all worlds with high quality and easy carry. I have been changing lenses on a PK mount since it was introduced, and I can just about do it in my sleep. I did have to have a thorough sensor cleaning at one point. I never missed the 3mm on the wide end enough that it remotely made sense to me to carry the DA 12-24, though I will admit that I am big on traveling light, sparing my shoulder and not offering a target. (I was spending several days in Barcelona--beautiful city, but known for theft from tourists) I also packed the kit lens as a backup and an especially low value target.
However, if I were on a crutch, I would probably take my 17-70 and forget it, or go out a buy the DA 18-135. If I took the 17-70, I'd pack the 55-300 for the sporting event. To go with the zooms, I'd throw in the DA40 for a lower light option and maybe the DA15 for a wider option. I was surprised how many of my shots ended up through the DA40, and it takes up no room. In fact, the DA Ltds are all so compact that you don't lose much having all of them at least on the trip.
Having also spent the last 3 months recovering from a serious accident, and still wanting to live an active life and take quality photos, I find a one lens option invaluable--even if it is a single prime and I am back to my equipment for my first trips in the early 70s. I can do better than that now, and at less than 100% mobility, I would probably buy the DA 18-135 in a heartbeat if I were taking a long-planned trip. All of the advantages of primes pale (IMHO) in comparison to the disavantages of changing lenses frequently without unimpeded use of both hands. Seeing a lovely Ltd prime bouncing off a sidewalk does not enhance the experience. I know this from recent personal experience.
