Not by too much - and I do believe 50's are the new 40's!!!Or something like that, anyway... Now you come to mention it, I'm still having trouble grasping the notion that my DH and myself will be 48 on this cruise!!!
I started saying that when I was close to being 50 too! Still, I do think of my parents when they were 50, and can't imagine them snorkeling or doing many of the things we do.
We already booked 4 people with Jay (not sure if he is "Harv" or "Marv" this year ... they alternate each year). They have four boats and four skippers, so there should be plenty of room for all. There are also bigger boats that take 50 - 60 people out, and those boats might be better for anyone who is afraid of motion sickness. The waters are pretty calm there, but you do get more movement on a small boat than a large one.
I haven't seen the list of excursions Disney is offering through the ship. I'm assuming they match up with the ones offered by the other lines. We took one that included a train ride up to the Canadian border, and then a bus ride into the Yukon, but it was not to our liking. Too much time on a bus for us. After that excursion, we canceled our similar excursion in the third port and did a walking tour of the town. We enjoyed that much more!
But our favorite was the whale watching with Harv and Marv's. I can't wait to go back!
