Joe's information on the Shuttle will be helpful if you are organizing your own hike.
If you are looking for someone else to organize the hike and take you from door to door, there are two options: 1) COMMERCIAL, and 2) CLUB.
Commercial operations organize hikes all the time. For the commercial option, I suggest using Google and searching on "Grand Canyon" hike guide
(or some permutation thereof).
My search turned up a list of sponsored links on the right of the search results. Four of the sponsored links provide the information for which you are looking. For a price I'm sure you can get what you're looking for.
For info on these operators or if you are not getting your question answered here on HAZ, you might want to join the Grand Canyon Group on Yahoo.
Several of the hiking clubs organize Rim-to-Rim and/or Rim-to-Rim-to-Rim trips - usually in late spring and autumn. You can access hiking clubs here on HAZ on the MAIN Page on the MEMBERS line where you see the word GROUPS or by going to the MEMBERS box and clicking on the right of the drop down box then clicking on Groups. You would then need to look at each of the Group Calendars to see which Group is organizing this hike. Or you could contact the clubs to find out if they are planning this hike in the future.
The problem is that these RtoR hikes can be several months in the future and not appear on the Group calendar until the month of the hike. For instance, XYZ hiking club may be organizing this hike for early October. It would not show up on the XYZ Club calendar until the October Newsletter is distributed. This is considered an "A" hike on most club Hike rating systems. The "A" hikers likely to hike this hike will be talking about it and organizing it well in advance. If you are an active A hiker on A hikes, you will know about this hike well in advance, otherwise you may not know about it until a few days before it is listed. Some clubs limit hikes to 15 hikers, so this hike might be filled up before a casual member or non-member even knows about it.
One of the best benefits of belonging to a hiking club is meeting other hikers who become friends and who organize their own "off-calendar" hikes all the time. I belong to two hiking clubs. I consider the club dues a great investment since I save on gas and car costs; I consider my club participation a great investment since I get new hiking friends and knowledgeable hike leaders for hikes I would not otherwise attempt.
Hope this answers your question.
