The indigo dye activity is $12 and includes the tshirt.

Yes, you can ride your bike. There is a newly constructed path that leads from RT 278 or Jarvis Creek Park right on to the Museum property. Inside the property, there is a paved path almost the entire perimeter. Be sure to follow traffic light signals when approaching the entrance. Lots of drivers in the area are visitors and are not always aware of bike riders or pedestrians.

I would at least spend 60-80 minutes for outdoor exploration as well as the museum.

The official answer is we have wheel chair ramps into all the buildings and there is a gravel path almost the entire perimeter.

Neither. We just walked around the grounds.

Most of the site is outdoors. The main museum is indoors but several of the exhibits are outdoors.

We did a 6:30 kayak tour and we did see a couple of dolphins. You might have better luck on the cruise. I still throughly enjoyed they experience we had.

My husband and I took 4 of the tours listed on their Winter Program Schedule in the past week: The Island's Story, Forts of Port Royal, Civil War Era, and Honey Horn History Walk. All are lead by museum docents and as one might expect, the information gained is dependent upon your prior knowledge and the strength of the your tour guide. With that disclaimer in mind, I would rate one of the tours as excellent, two within my level of expectation, and the last as leaving much to be desired. As I am not aware of how these various tours are assigned or whether different docents might lead these group at different times of the year, I really cannot be more specific.

There is a (voluntary) suggested donation of $5 per person

Yes. Attended to courses they offered - snakes and spiders. Have not attended the Beach Discovery Tour, but I'm sure it's great. Have fun!!
