I spent a week in the sanctuary on the Discovery this April. The cabanas are very nice and cost $220 per full day and $140 per half day. This covers 2 people in the cabana. No discount for solo. No discount for booking the entire cruise. Loungers are $40 per full day and $20 per half day and are discounted to $30 per full day if booked the entire cruise. Prices are the same on sea days as port days. On Alaska sailings the price of loungers will be increased on scenic cruising days such as Glacie
