Hi, we are going on the Shark Ray Alley excursion at the end of January (Norwegian Sea). We've booked our excursion with Coral Breezes Limited (www.coralbreezeslimited.com). I think it is $69 per adult for 5 hours including lunch. We've read a lot of great reviews on Coral Breezes but we'll let you know when we get back if it was as wonderful as it sounds!
