My Deam Vacation

my husband and i will be leaving to the bahamas at the end of aug. we will be staying at the atlantis and i know there are a lot of activities on the resort. but we wanted to travel around the island. are there any activity packages we can purchase when we get there (or before we get there) that will save us some money on activities and/or food? tours, cruises, etc. also what are some fun activities we can do there that are not water activities. i cant really swim that well but my husband can do the water activities
