My wife and I are trying to book a combination Kili climb and safari for 2011. Although we feel inundated with information, I believe we've narrowed our choice of companies down to two (if not three). We would greatly appreciate any input we can get. We're big planners, so we'd rather have everything set up before our arrival in Tanzania (for those of you who are just going to suggest waiting until we get there).

Tour Company List:
Duma Explorer, Inc.
Summit Expeditions & Nomadic Experience (SENE)
Real Life Adventure Travel

We may be ruling out Real Life Adventure Travel simply because we cannot seem to find any reviews for the company online.

One may seem to be more expensive than the other, but are there additional perks that comes with paying more? We'd appreciate hearing from anyone who has had experience with any of the above companies on either a climb or a safari (or preferably a combination).

Thanks in advance!
