Travelling to Switzerland and Paris as a travel noob.

We had a travel agency make this Itinerary and they’re also booking the hotel and train tickets for us. The cost comes up to 2850 Euro per person and it includes accommodation of 4 star hotels and 2 rooms (we’re a family of 5), 8 day Swiss pass, and the train ticket from Paris. Do you think this is worth it? And how does this itinerary look?

Itinerary:

Paris: 21st May - 24th May

Interlaken: 24th May - 27th May

Engelberg: 27th May - 30th May

Zurich: 30th May - 31st May
