Two yacht option seems pretty different

We’re looking at a crewed week in late May, and the two options sound pretty similar on paper, but one is noticeably less expensive.

Both are described as all-inclusive, and from what I’ve read, that usually means a captain, chef, meals, drinks, and water toys. I’m guessing the details vary depending on the boat, though.

What should I check so there aren’t any surprises once we’re onboard? My husband is especially excited about the jet ski, so I want to make sure that’s actually available.
