We were in the parks June 4, 5, 7, 8, 11, & 12th. We saw dream team members several times, mostly just walking around talking to folks, the kids actually did some pin trading with two of them - this was during "no white vest" time but they were still carrying their black dream team bags. We were in the parks from opening to close (one park per day) each date, just seems like the prizes aren't as plentiful.
We didn't see a whole lot of dream lanyards, ears, or fast passes, nothing compared to March of 2007 when we were there.
We did have this experience at DHS on Saturday June 7th during SWW. We were at the park well before opening (8:00 AM to be exact) - they allowed us in so far at 8:30 and we had to wait for another rope drop. We headed straight away to sign DS up for the Padawan Mind Challenge and then on to Star Tours as the wait was posted at 5 minutes. DD won't ride so we do child swap, DH & DS ride first then hand DD through the simulator to DH and I sit down with DS. As DS and myself exited the ride (we were in the pod fartherest to the left if you are facing them) I notice 4 dream team members standing outside the pod next to us, I'm telling DS "it's the dream team, it's the dream team". We slowed our pace a bit, thinking they might be getting ready to pass out lanyards or FPs. They just stepped back and allowed everyone from our pod to exit. DH & DS were shopping in the SW store, I kept watching the exit from the ride and shortly they exited with a family of 3 or 4 so it must have been a biggie (probably the night in the castle).
Both the kids got a YOMD Tink pin from one of the photo line CMs while waiting to see Snow White or Mulan (I forget) at Epcot.
