What happens on my first float? What do you wear in a float tank? What should I bring to my float? How should I prepare for my float? How early should I arrive for my appointment? What if I get salt water in my eyes? Should I check with a doctor before floating? How do I book a float? Can I bring a friend? What if I am running late? Do I need to sign a waiver? What should I do after my float? Can I float twice in one day?
