I was a little skeptical my first time. I generally find it hard to focus so it was a little tricky getting used to the Pod. But about 3/4 of the way thru I really relaxed. The staff was so cool and friendly explaining and answering everything you could possibly want to know.
I can see if you're claustrophobic... it could be scary but you can leave the lid open.
I joined the club with a membership and every time since then has been incredibly relaxing. I love it and I've got to take some friends here as well and they all become fans. You've gotta give this place a try because it's been a huge blessing for me!
