I'm going to be in Lausanne for a weekend at the end of October. I'm looking for a hotel with a decent pool 20+ metres. Anyone have any recommendations?

I have a recommendation to avoid after a negative experience: Hotel Alpha-Palmiers

Avoid!

According to TripAdvisor, there are 5 hotels in Lausanne with pools: http://www.tripadvisor.com/Hotels-g1...ud-Hotels.html will help begin your search.

I'd choose the Lausanne Palace and Spa.
