I would be inclined to drop the therapies, except maybe the social skills. But would frame it with school (and your DD) as a "break" (4 weeks?), and unless that is a grain success then try re-introducing the ones you miss most and pruning the play dates. Though I'd possibly prune the play dates a little too.

From my perspective the play dates sound important to maintaining school success, for the reasons you've stated, so I'd try dropping them as he second experiment.

Good luck!
