hi ther, i am cruising on the Island Princess this fall to alaska and I have a regular balcony room (not the mini suite). I have read something about the showers, and saw a picture of one. Looked odd to me. there was no "wall" per say to enclose the shower. Is this the case? Then I read soemhting about the shower curtain needing to weighted down. Is this true? Just want to be prepared.
