Currently, the CCR PTN Dining Package is $99 per adult and $45 per child.
For the OP: it should be possible to see F! from the HC viewing area if your daughter is in a wheelchair. Or, as mentioned above, you could view from a table on the RBT patio with the RBT Premium Dining Package (dinner while seated at a table on the RBT patio for the first show -- reserve by phone only).
For the Pixar Play Parade and PTN, you could view from benches along the parade route without a dining package. For the PPP, there is good bench seating by the Alice in Wonderland restrooms, across from Matterhorn. Or you could invest the time to get a bench by the Hub or by the train station. Investigate the parade routes in DL and DCA earlier in the day to see where you'd like to sit, then make sure to hold those spots before the parade. I'm pretty sure there are HC viewing areas for those in wheelchairs -- ask the CMs where these areas are located. For PTN, you should be able to grab bench spots somewhere on the route with about 2 hours or so wait time (possibly less time depending on the day and which showtime). I'm not sure how much time you would have to invest in DL with PPP -- try asking CMs who work the parade route.
For WOC, there is HC bench seating (ask the WOC CMs about this) with a good, big picture view. Your daughter will be allowed to sit, and you will be allowed to join her if the area isn't crowded that night. But if other guests need to use the HC benches, then you will be asked to stand. For a guaranteed seat, the WOC Dessert Party is a very nice treat. There are high and low tables, so if you decide to do this, note on your reservation which height table would be easier on your daughter. High tables have tall director's chairs and low tables use regular chairs.
