I definitely think Lighthouse Point is inferior to Castaway. I wouldn't mind doing a cruise that went to both islands, but I would definitely never again do a cruise that only goes to Lighthouse Point unless they fix some of the glaring problems (long pier walk with no shade and no option to wait for a ride unless you have a specific type of qualifying medical condition, insufficient loungers on the beach itself as opposed to behind the dunes, dining kiosks where you have to queue up individually for different food items leading to long lines, insufficient seating in dining area and lack of shade generally).
The walk isnt terrible - no worse than rope dropping our favorite ride at WDW.
They may have changed the ride options - I remember hearing/seeing something about booking a ride from the ship across the pier. On the way back, one of the golf carts actually stopped and asked us to climb on. Not sure why we were picked, but we didnt turn down the ride. They were shuttling people back and forth, and there was no line at the waiting spot.
Lighthouse Pro's:
-Warmer water (December trip)
-Pink Sand
-I liked the BBQ foods...
-So many chairs on the beach
Lighthouse Cons:
- Kids activities in the water are limited to just swimming
- Trash in the water - there was a lot of floating plastic.
- Longer walk to get drinks (from where I was sitting) - yes they have beachside service, but i like to go up to the bar
Castaway Pro's
-Kids swimming area has activities / playground in the water
-Closer walk to the bar(s)
-More shopping
-View of the ship from the entire beach
Castaway Cons:
-Water was cold (December)
