I stayed in Zuerich last week and was very impressed with a hotel called Dihei in Duebendorf. The hotels within Zuerich were very expensive for the time I booked, but Duebendorf is within the Zuerich Card travel area and has trains every fifteen minutes until very late in the evening. Comfortable beds and a nice buffet breakfast. Note that as it's a local hotel it has Swiss power sockets only, so you'll need to get an adapter. (Swiss sockets are not the same as in most of the rest of continental Europe.)
You must have some older euro adapters. If the base of the adapter has pointy ends like this it will work just fine in Switzerland.

No, that's what you get in more international hotels. Swiss sockets have three small round pins. https://www.power-plugs-sockets.com/switzerland/
I was on a Rick Steves tour, so nothing too fancy. The 2 prong adapter fit in all the Swiss sockets.
I’m not an electrician so it would be interesting to hear from one but I keep reading that yes, the two prong adapters work but the third prong on the Swiss is for grounding especially in the older buildings.
Confirming what Iiz has stated. The 2-prong adapters with the pointy ends work just fine in Switzerland even though the outlets have 3 holes.
The Switzerland tourism website also confirms this:
The standard continental type plug with two round pins, applied for
many electrical travel products, may be used without problem.
I have many European adapters which I have accumulated over the years and take a number on each trip. Most of my drives include France, Germany, Netherlands, Luxembourg and Switzerland, and as often as possible Italy and Austria.
I can promise you that a couple of months ago when I was in Oftringen, near Solothurn, in Switzerland, none of my pointy adapters worked. I had to borrow a multinational to Swiss chunky adapter before I could charge my phone or laptop.
I only say this as an example, having stayed in dozens of Swiss hotels over the years, that sometimes the only way out is to use a proper Swiss adapter. My special adapter which I bought many years ago at a Migros in Bern was still in the drawer at home.
Yes, I did have a European adapter, but it simply wouldn't fit into the small hexagonal recess in the Swiss socket.
