If at all possible, I suggest you visit the Florida Capitol during the legislative session. Although it is the time of year when the capitol is the most crowded, but it is also the time of year when the most is going on.
There are a few key floors in the capitol.
The 4th floor has entrances to the House and Senate floor. This is where the congress members enter and exit.
The public gallery is on the 5th floor. The basement and 10th floor have restraints.
The rotunda that starts on the main floor houses the seal of Florida and the hall of women.
A very useful directory is placed at the elevator banks that will tell you what is on the floor you are on. If possible, check the calendar and take your kids to a session of the House or Senate. Whether a committee meeting or full session, this is an opportunity to see civics in action. Explain to the kids how they can speak at committee meetings or more locally at town council meetings when they have concerns about the community. Remember to turn off electronic devices while in the gallery and keep talking to a minimum.
After visiting the Historic Museum and the capitol, be sure to ask your kids what things they have noticed have changed since 1902, the year the old capitol is restored to.
To enter the Capitol building you must pass through a metal detector and like all of the buildings featured here, the Capitol is ADA accessible from the Capitol Plaza side entrance.

Typically, the capitol is open Monday - Friday: 8:00 a.m. - 5:00 p.m. excluding State Holidays.
