HB is a great park to be near but not within the MB congestion. I agree entirely with the comments of the previous poster. Another plus - HB originated as the home of a very wealthy New York couple. The remains of the home can be toured for a small entry fee. The home is in a Spanish style that is an interesting example of an upscale early 20th century home. Too bad it has not survived in its original glory.
Brookgreen Gardens has a lot of art displays, some of which was produced by the wife of the HB owners. You can also take a boat ride showing original rice fields as the Gardens were created from three former rice plantations. Extensive information about the culture of the slaves used to operate the plantations also exists. On one visit my wife and a couple of friends spent two days touring in the Gardens.
HB Park is devoted more to serenity and art. The MB Park is more a regular beach park. It is located very close to the ocean and at the south end of the MB beachside road. One problem is that the airport is nearby so there is jet noise. Offsetting that is a fishing pier that was free when we visited about 10 years ago. I would take a family to MB Park because it is near to more attractions; for a couple HB is definitely a better choice.
