We are taking our first Disney Cruise on June 27th and are trying to decide on excursions. Mainly, we just want a nice beach day when we are in Nassau (it is just me, my husband and our 9 year old son). Does anyone have a recommendation between Blue Lagoon Island Beach Day and Atlantis Beach Day and Discovery Atlantis? The Atlantis one is $56 more in total and money IS a consideration, but if it is way better, I could spring for the extra cash.
