A financial advisor here in US is someone who can help invest in different ways, depending on your long and short term goals. A financial advisor should also specialize in tax laws and how to get the most out of your investments. Which could be why the LLC was formed so late in the game, Disney Fantasy guy recommended it.
Even if they made 10x as much as we think they did in their successful years, I do not think there is any chance in the universe that at 39/40 years old, they are "all set" for retirement. They don't spend $100s or $1000s at a time, they spend $10,000s at a time. The Roy O suite cruises, the Tesla, Aulani trips, the solar panels, this backyard reno, the future Rivian, all huge expenses and what they are bringing in while they are spending all this doesn't even come close to what they were bringing in 3-5 years ago.
I do believe they have a FL prepaid account for at least J$, but that is not a lot money saved in the grand scheme of things. I also do not believe they have any idea what 2 kids will actually cost them over the next 18 years.
