Let's have some fun with some simple math*
Mermaid ride: 7min
Mine ride: 2min(very generous?)
20K 10 min
SWSA 2 min and 20 seconds
So between the new** Mermaid attraction and the mine coaster we reach 9 minutes of time that the wan- oh I'm sorry other "guests" aren't in your way staring at a map. Almost 20 years ago said guest would be occupied for over twelve minutes plus. Now I don't have capacity numbers to bandy about*** and I am guesstimating based on a very brief video put out by Disney, that capacity of the rides/the amount of time occupied has decreased. Any local theme park that might be okay, however Disney**** is now "welcoming" more guests than ever and decisions have been made to cut the overall attraction time in the park.
* rounded up in favor of current attractions.
**Been open for two years, but by Disney's "temporary" standards it's still a newborn.
