Has anyone purchased one of these before. Thinking about renting one on our August Sailing on Oasis of the Seas. We are going with a group and hoping to rent 2 of them across from one another so we have a home base. Any new pictures of these or thoughts? They are $199 on sea days, which I was hoping it was $199 total per day not per individual. Seems like the pic shows 2 loungers. Thank you!
