OK,
@StarBurst asked about going thru the Panama Canal on the Wonder.
My first comment would be just what an amazing technological achievement the canal is. These days we seem to have trouble building simple infrastructure like roads and bridges. To think that this wonder of the world was built a century ago is truly mindboggling.
Now, one thing I have figured out is that despite common belief that you need to be up and out on deck at 6 or 7 a.m. when the ship hits the Gatun Locks (the first), I would advise sleeping in and waiting to spend time later. Sure, you 'miss' the start of the Canal, but the whole experience is what makes it interesting, not simply entering the locks.
To see how little room there is on each side of the ship (about two feet) for the Wonder, a Panamax class ship, is also amazing. You were literally waving and talking to Canal employees on land that you could have jumped (a very short jump) off the ship onto.
The weather is extremely hot and humid. Look where you are. Gatun Lake is beautiful and resembles any TV show or film that seems set in the Rainforests.
Disney, btw, printed out nice individual certificate for every passenger (signed by the captain and some rodent) that says that we all crossed the Canal. They also brought a Panamanian official onboard to stamp passports, which was a little strange because, technically, none of us actually ever set foot in Panama (the only countries we visited were Columbia and Mexico). It was still kewl to get the stamp considering how many countries I visit that I never get a stamp in (mostly EU).
DCL had plenty of coffee and water and continental breakfast items available on deck and the characters ... Mickey, Minnie, Pluto, my new second-best gal pal Daisy, crazy chipmunks Chuck and Dave ... were around all day off and on.
It just is such a bizarre and awesome experience to start a day in the Gulf of Mexico and end it in the Pacific Ocean.
As an aside, the amount of wildlife that you can see once the ship is in the Pacific is fantastic. Whales, dolphins (swimming alongside), sea lions, seals, sea turtles (these I didn't personally see, but everyone else seemed to) ... you just don't tend to see the amount and variety of creatures when doing Caribbean or even transatlantic crossings.
I don't know that I'd be in a hurry to repeat the cruise, but that has nothing to do with the experience or DCL and more to the fact that I am not sure that 15 nights of cruise line food is good for my health!!!
