I understand. And even if you have finalized your plans, they may change while there because of the weather, for example. Anyway, I think it helps if you read the pass pages I linked to: you can see how the passes work, what's included and which concept appeals to you most. The Swiss Pass promotion may actually be a good deal for you: your children will travel along for free (with the Regional-Pass you need a CHF 30 Junior Card for the 9 year old), the legs Basel to Wengen (from Frankfurt) and Wengen to Domodossola (to Milan) are free, trains, buses and boats (recommended, great for kids, see here) are free, museums are free, and cable cars are discounted. The Schilthorn (I suppose that's what you mean) is discounted by 50% from Mürren. The trip to Mürren is free. I think it is worth to look into the Swiss Pass now that the offer is available.
