I also will push for more attractions. However if you look at it from strictly a capacity standpoint, they could see a large increase in hourly capacity without factoring in the restaurants or meet and greet attractions, which may simply offset the capacity lost by removing Mickey's Toontown fair:
Ariel's Undersea Adventure: Omnimover, probably around 2000 an hour
2nd Dumbo Spinner: 600-800 additional capacity per hour
Modified Barnstormer: Probably no increase
Pixie Hollow C Ticket: Could be 600-1000 per hour
It's not a DCA level increase, but it is still quite substantial. If given the choice of another D/E ticket in Fantasyland, or another D/E ticket elsewhere on property I'd vote for the latter.
