I've had the Bamboo Massage a couple times and absolutely loved it!!! I was in a different situation in that I had an injured back (a fractured sacrum... yes, very bad timing to be injured like that before a cruise!). Because of my back injury, I had significant muscle tightness in my upper back and neck/shoulders, and even my legs were sore because of how I had to walk due to my injury. I went to the spa and asked if there was a massage that was best for my situation to help my muscles relax and just help me be more comfortable. They recommended the bamboo massage, but they said the therapist would do it with very light pressure, except in areas that weren't near my back (ie, she used higher pressure in my legs and feet, but it felt good because my legs and feet needed the deeper massage).
Boy, it was AMAZING!!!! I asked for the most experienced massage therapist, first of all, because I really wanted to make sure the person knew how to handle me due to my injury. I had a massage therapist named Kathy and I believe she was from the Phillipines. I HIGHLY recommend her if she is on the ship you are going on!! She has her physical therapy liscensce as well as her massage therapy liscensce, so she really understands the body well.
That said, I think the bamboo massage is meant to have high pressure, BUT you can ask for them to do less pressure if that is what you like. You don't need to have a massage where you are hurting the next day because the pressure is so high, unless that is what you like.
For me, I went into the massage with extreme muscle tightness due to my back injury and when I left, I was able to stand up straighter than I was before I came in and the pain in my back was less after she was finished than before she started. The massage itself was just SOOOOOO soothing and relaxing and never once did I feel like the pressure was too high... I would just tell her if the pressure was too much, and she'd immediately do less pressure. They use these warm oils with the bamboo sticks, and it just feels sooo good and so pampering!
So, I recommend the bamboo massage. Just communicate the level of pressure you want. I would totally get this massage again without a doubt.
Have fun!
