Two days itinerary – Should I include Zaanse Schans?

We family of 4, will be visiting Amsterdam as a part of two weeks Europe Trip in September third week. We are planning to spend two full days in Amsterdam (3-nights stay). We reach Amsterdam 8.00 PM from Prague and I have booked a hotel near Sloterijk Station (Xo hotel park west). We just take rest on day 1. Thinking of buying group pass for tram for two days. The followings are my detailed tentative/ plan for next two days. Will be flexible to adjust depending on weather. Let me know if this plan is too aggressive. We are thinking of visiting only one or two museum and no De Wallen area. Is Zaanse Schaans trip is too much for a two days trip?
