i'll be at citywalk with my child while others are enjoying hhn and i need entertainment ideas. i'm thinking about seeing a movie but i still need to find another activity for us to pass the time. do the boats only carry on-site hotel guests? can you explore the hotel grounds if you are not a guest? also, how is the security at the parking garages during hhn if we have any wait time in the car (trying to avoid that)? thanks.
