I think it is a little presumptuous on your part to judge what my kid can handle or can't. I am well aware of how loud airplanes are as well as my son's tolerances. If this is something that I think he will not only tolerate, but enjoy that is my prerogative. I don't think I was asking for opinions if people thought it was a good idea. I was letting the OP know what our plans were.
I have literally traveled ALL over the world (not cruising) and you wouldn't catch me dead on one of those generic "tours". Hopping on and off a bus with with 50 other people all day sounds like a great way to torture my enemies. Fine for the people that prefer to travel that way, but not for me or my family.
The tour suggestion wasn't for you. I always try to put extra spacing to separate thoughts but I suppose it didn't translate well this time. Regardless, Bernard's and Joyce Prince don't have 50 people on a given tour, and there are options to make it your OWN tour. If you are already researching I would hope that you noticed that. Joyce doesn't do generic tours at all, and even on the non-private Bernard's tours there is often the option to change things up. But the op asking about tours or things to do is at the beginning of research, hence the suggestion of tour companies.
You described your child as unpredictable. I personally would rather have my own shuttle and driver that could get to know my little guy, who has a vested interest in keeping him happy, and who can change things up if needed*, rather than relying on finding a taxicab at the moment I need it!
And you might notice that I'm using the "I" word. I'm not using "you" except to point out your words. *I can't imagine it. I would do this. I wouldn't do that.* That is not presuming. That is not judging what your child can handle. That is me imagining my former 2 year old or any of the many little ones I've known, at Maho beach, and thinking about how freaked out those kidlets would have been, and trying to HELP a total stranger.
We don't always think of everything. We sometimes get caught up in vacation plans and forget about the simplest things. Been there done that, repeatedly, and it's all embarrassingly documented in my trip reports! I'm not dictating to you, I'm trying to help. Maybe you didn't think about baby ears while basically standing on a runway. Maybe you did and are planning to bring ear protection. You didn't mention it. So I can't know.
Many of my posts are about ears and sounds. I've noticed that with me and my son (and so many others), being overwhelmed and unhappy starts with too much sound. In the middle of a massive kid tantrum (and a DH reacting poorly to it) I suddenly heard how loud tomorrowland at DL is. The ambient sounds really add up. For some reason I had my sleeping earplugs in my purse. I told my guys to stop talking, put the earplugs in DS's ears, and he calmed down instantly. We now carry them for all Disney trips. I'm always shocked how many people think that's a fabulous suggestion; that they never thought of how noisy things are, and never noticed the connection between noise and being overwhelmed. (That tantrum also went along with huge hunger, just to tell the entire story, and we learned from that, too!)
So it's not a surprise to me that the baby at Maho idea would cause me to wonder if it had been thought through and to try to help! No judging or presuming apart from having known many litttle kids through my life.
Didn't help you; maybe it will help someone else.
*not to mention that those tours tend to have rum punch. (Autocorrect keeps changing that to "lunch" haha) My kid's early years would have been more fun for me if I'd had more rum lunch (punch!) in my life lol.
