Water birth experience??

I have an almost six year old that was born in the hospital and it wasent the best experience. I am 9 weeks and have decided to do a water birth! We did a tour and it's so laid back you have your own cottage with a big jacuzzi and bed. It smells so good when you walk in dim lights relaxing music you take your shoes off when you go in...all classes are required. Mommy and me lactation and a few others. They made it clear they are prepared for any medical emergencies and they are all about its YOUR choice through out the pregnancy no one elses. Any experience with water births not gonna lie I'm a tad nervous.
