Just got back from Ecuador, was on the 8/31-9/6 Aggressor II charter (followed it up with a trip to the Ecuadorian Amazon, highly recommended), and things changed even while we were there. On our first morning at Darwin, we were told by the DM that the PNG had just approved a new itinerary that allowed only one boat (or operator, since Agg I was up there at the same time) at Darwin on a particular day. If true, this would allay concerns that Wolf/Darwin would be deserted and open season for fisherman for days at a time. Not sure if true or not, but Deep Blue did not show up until we were leaving Darwin.
Also, changes in dive sites. No more diving at Seymour, so diving is at the sand spit called Mosquera between Baltra and Seymour. Also, were told that a snorkeler was bitten by a sea lion at Plaza, so no diving allowed there either.
Other things we heard from the DM (Solon Intiago, originally from Deep Blue) confirmed that as of 2008, there will be no dive/land tours. Dive only, or land only, not both (as an aside, both trips I've been on we did Wolf /Darwin and 4 land tours incl. Darwin Res. Stn). Also, this wasn't clear to me but it sounded like there's discussion that all diving has to be done by noon, to accomodate snorkelers. This didn't make sense (who snorkels Gordon Rocks... or Cousins? or Seymour? maybe someone does) but it would wreak havoc if you had to finish diving by noon and couldn't land tour.
At any rate, looks like things will change somewhat over the next few months. It'll be interesting to see how it shakes out. Although there are many places to go in the meantime, looking forward to going back someday.
