Kids are out of school and you're trying to fill the summer days, but the Florida Aquarium has a deal for those summer nights. You can get into the aquarium for only $15 after 4 p.m. every Thursday this summer (after 5 p.m. on July 4) starting this week. The aquarium, which normally costs $21.95 for adults, $16.95 for kids, will be open until 8 p.m. and you can catch a show by the Florida Aquarium Mermaids at 5:30 and 6:30 p.m. Bring swimsuits so the kids can splash around in the Explore A Shore outdoor water playground, and there will be family-friendly live entertainment. The aquarium is in the Channel District at 701 Channelside Drive, Tampa. Call (813) 273-4000 or go online at flaquarium.org. The Summer Fun Nights special runs through Aug. 8.
