My 8yr old and I adored Blue Lagoon! We liked it much more than
Castaway Cay. Why?
1. Because it was not at all crowded. You could get a chair or hammock right by the water and not have to be packed in with tons of other people. Who wants to lounge around looking at the backs of beach chairs? With kids in tow at CC we could not move fast enough to score chairs in the first rows on CC
2. it had inflatable bouncers in the water to play in (extra fee) that were in shallow enough water that little kids could enjoy them (waist height on a 5'3" parent at deepest point, one was anchored waist height on my 8 yr old) My daughter loved them!! She did not like the slide at CC because it exited too high above the water and she said the landing hurt and was scary because it was dark and deep.
3. You actually knew you were in the Bahamas. The place is run by locals, served up super yummy conch fritters and cinch salad, has real coconuts to eat and drink, steel drum band etc. CC is just Disney and so-so american BBQ fare. Place is laid back and a little worn around the edges in a thoroughly natural and pleasant way.
4. The sea lion encounter was well run and it was fun to be able to watch the dolphin swims. There was a nice touch tank near the sea lions.
5. The boat trip out was fun. You got to see the port and surrounding houses a bit. The water was so clear you could almost see the bottom
6. Not great snorkeling, bottom is white sand and some eel grass, but enough fish to be interesting.
The cons were:
1) Took a long time to get sea lion photos. Do not wait till last minute to collect them!
2) Not enough time for beach if don't arrive early. We could happily have stayed all day.
3) Extra charge for inflatable bouncers area even if you have booked expensive seal lion/dolphin
4) Have to buy food and drink tickets at bar then go to cafeteria next door. Not a long walk but you need to go back and forth to see menu, order from bar, get food, back to bar if want anything else, back to cafeteria etc. The seagulls stole all of our conch fritters while my back was turned necessitating additional bar to cafeteria trips
But all in all I liked BL enough to wish flights from NYC to Nassau were cheap enough to go back for a short trip.
