I did a 90 minute float in Vancouver last year. Feels like you are laying on a liquid mattress. With the earplugs on the only sound I was conscious of was my own heartbeat. My only complaints was that water seemed to cool off. Also, the music they played to wake you up was a bit too loud. A one and done thing for me, as it's a bit too pricey. For the price of the float I could have had a steak and lobster dinner, including drinks.
