can anyone offer any advice/share their experience using a salt water floatation tank in toronto, like float toronto on queen?

I was gifted a set of floats and have booked my first one. Wondering if anyone has any advice, tips, tricks, or could share their general experience? cheers!

edit: i went and it was awesome. so relaxing and my skin is super soft. they were incredibly professional and informative, and it was a top tier experience for me. thanks for all the info folks!
