Be prepared to walk (and bring a stroller). The mansion, marine museuem, and planetarium are sprawled out over several acres. Set low to the ground (convenient for toddler viewing!), are the colorful exotic birds on display in the mansion. The planetarium holds frequent sky shows. Summer workshops are available for the pre-K set (starting at age 3) and from K-grade 3. See site for details. Adults, $5; Children $2
