I'm unable to view that I'm sorry unless if you taken screenshots from
Disney cruise websites of prices in the past.
I can give some advice if you want to get a cheaper rate for a Disney cruise.
Book early as possible nearer to opening day because you get to pay a deposit and select a stateroom at the same price as last minute guarentteed stateroom with restrictions.
Maybe join a Disney vacation club.
Maybe find a
Travel Agent something like
dreams unlimited travel because you'd get onboard credit to spend on the ship.
Maybe if you are on the ship get an placeholder on the app and call
Disney cruise line when you book your next Disney cruise and give out information that's on your placeholder. Placeholders can also be transferred to your Travel Agent too within 30 day's.
If you are a resident in Florida or Canada Disney have reduced rates near to sailing date.
If you are part of the US military Disney have reduced rates near to sailing date.
