I live in CH, knowledge of the basel, zurich area and pretty good of luzern grindelwald interlaken area.
Pretty much any campsite will be of a very high standard so no concerns there. All will have a pitch up and see system, you can also call on the day if you are not close, majority will speak English.
Interlaken is a tourist town but has some decent campsites. Grindelwald was a campsite but again a tourist town as is the whole area. If you want a stop over for few days and do nothing then look at lauterbrunnen otherwise consider interlaken or luzern.
Remember the 40chf vignette is only for the motorway.
