Late October is not the best time to spend holidays in Switzerland as the summer is over but the ski season has not started yet. In addition, it can be quite rainy and already chilly in the mountain regions. Some hotels even close for this time of the year. You may most likely find a nice weather in the Ticino region of Switzerland (Italian speaking), which has its own microclimate and is around 3-4 hours from Zurich by car.
Anyway, if you are happy to spend most of the day in a hotel spa, there are plenty of nice hotels in the area around Zurich (either Switzerland or Austria). You can search and also book on the following websites:
