Cruise ships you stay on property and are transported around from your hotel and have all day entertainment.
You can compare WDW to any destination that has...
- Rides
- Shows
- Costumed Characters
- Dining
- Hotels
- Airports etc
So you can compare WDW to Six Flags, Sea World, State Fairs, Circuses, etc. You really only need one like characteristic to compare.
I have said this several times before over the last decade, but when you compare Six Flags to WDW, Six Flags wins in several criteria. Maybe not all. Maybe not overall. But in several ways Six Flags is superior to WDW.
