Review for Treasure Island Resort & Casino Review For Blue Lagoon Google User May 2 '18 at 3:26 It's not worth the hype. You have to make a reservation days in advance. Even in the off season. The change rooms are way too crowded. It doesn't have the Icelandic feel of other baths. It has a feel of a super touristy place. I mean people go there in bus fulls. Lock up everything or it will go missing! View full site to comment or like
