Georgia Aquarium lists Haunted Seas After Hours for Friday, October 16, 7:30–10:30 p.m. The event includes aquarium galleries, a live DJ, seasonal décor and both alcoholic and nonalcoholic drinks. The published advance nonmember price is $49.99 and member price $29.99.
This is a genuinely different date-night experience, especially if the normal aquarium crowds make the exhibits less appealing. The setting is the draw, not the drink program.
What to do: Check remaining admission for Friday and decide whether seeing the galleries after dark is worth the event price. Nonalcoholic options are explicitly available, so there is no need to plan the evening around alcohol.
Before you go further: This is an 18+ event and a separate ticket from daytime general admission. The venue lists last entry at 9:30 p.m.; parking costs extra.
