Cordie and I had the opportunity to try this out when we were in Orlando recently for a conference of his. This is what the pod looks like and you enter it by yourself for 90 mins of silence. 
Below is a great read that we both read before floating… It has some amazing health benefits:

Both of us really did feel the ‘detox’ part as we ended up getting sick from it (or if it was from going from extreme cold weather back to quite warm temperatures) and felt like we were detoxing for several days after the fact.

The area that the spa was in is called “Baldwin Park” and it was a very quant place to walk around… the girl working had a 10 month old puppy chihuahua – his name was Booker and definitely increased our desire to get a puppy for ourselves… hopefully in the spring.
Have you tried the sensory deprivation/isolation tanks/salt floats? If so what did you think?
Cordie and I both enjoyed it but if we do try it again will go for a shorter amount of time.
