Visit an Aquarium
Visit a local aquarium for a fun afternoon. Often times they have exhibits where you can feed the fish, or touch the sting rays.
Local Concerts
Check your local newspaper for weekly events. Most cities/towns offer free evening outdoor concerts. Grab your lounge chairs or picnic blanket, take a few snacks, and enjoy a free evening of entertainment together.
See a Midnight Film at the Cinema
If you're lucky enough to have a cinema that has a late night film schedule, take advantage of it! Many times they're less crowded, giving your more 'private' time.
