The MoaTrek itineraries look great, but - I count 5 or 6 one-night stops in the itinerary, and only 1 or 2 three-night stops. One-night stops are, for us, torture and make the vacation less enjoyable (one or two may be unavoidable, but 5 or 6!). Of course, it maximizes the amount of 'stuff' you see, but it's just not worth it for us - forever packing and unpacking (or basically, living entirely out of your case), getting used to different beds, etc. The same applies to several of the other tours, including the one I originally posted (the APT tours - 6 one-nighters!).
The 'Mondumo' itinerary, OTOH, has only 1 one-nighter, and 2 three-nighters; much more in line with our preferences. The 'Odysseys Unlimited' itinerary also has only 2 one-nighters, and has 1 three-nighter. Obviously there's more to consider, but these are some factors that are jumping out at me.
Having spent 2 days doing a 'deep dive' now (still early days!) we are leaning towards putting together a DIY tour, and focusing on the South Island (using local tour groups / guides as appropriate). It looks like 3-4 nights (at least) in Te Anau (as opposed to Queenstown) is a good idea - getting us closer to Milford Sound and Doubtful Sound, and by all accounts a lovely place to stay. After that, perhaps using a rental car to drive to Wanaka, and then Wanaka-> Franz Josef -> Greymouth, and then the train to Christchurch, then fly from Christchurch to the North Island. Haven't explored much beyond that yet.
Regarding the 'cultural experiences' on several of these tours - I see several tours include visits to Maori sites, and include 'performances'. I've typically found these types of events to be somewhat 'hokey', or 'cheesy' (in Alaska, and elsewhere); - not sure how to explain it, but I get the impression the locals are getting dressed up in traditional costumes and performing for the tourists and the whole thing feels uncomfortable. Are these events enjoyable / genuine in New Zealand?
One caveat-the bus was an 18 seater so no spreading out like the RS tours but the drive days included a number of stops. The luggage was transported in a trailer hauled behind the bus. Our guide was also our driver.
That's great information! I absolutely LOVE the fact that on RS tours, you can spread out at the back! Does this apply to other NZ tours, does anyone know? Perhaps the roads don't accommodate bigger coaches? Having the luggage towed behind - does that result in your luggage getting a bit of a 'shakedown'? The guide being the driver also; I'm thinking that's illegal in Europe, is it not? We had that on a tour in Alaska, and I was always concerned that our driver was not paying enough attention to the road! The more I think about this, the more I appreciate how RS runs his tours in Europe!
