I found this on the cabanas
On the shaded deck are two comfortable lounge chairs, two more straight chairs, and another side table. Each cabana has a fresh water shower and one hammock outside. A basket of magazines, a selection of Coppertone sunscreen, and a bag of sand toys (family beach only) complete the in-cabana amenities. Each cabana has a buzzer that summons one of the attentive cabana hosts, who can provide refills if you run out of towels, soft drinks, or sunscreen, and who will page a bar attendant if you want to place an adult beverage order. Our hosts checked on us several times during the day just to make sure we had everything we needed, but were never intrusive. Bar servers also roamed the beaches, offering beverages and discreetly checking for wristbands.
The family cabanas share a private beach that is well-furnished with sun loungers, chairs and umbrellas, and stocked with floats and rafts; bikes and snorkel equipment can be checked out at no charge from the nearby rental locations. Serenity Bay cabana guests access the adult beach via a gate (really just a rope) in front of cabana #19, and the floats and rafts are stacked next to each cabana. Bikes can again be checked out at the Serenity Bay rental location.
The cabanas on the family beach are $499 for up to six guests (including children), and you can add up to four additional guests to some of the cabanas for an additional $50 per person. The adult beach cabanas are $399 for up to six guests, do not include the sand toys or snorkel equipment rental, and you are generally not allowed to add additional guests, though exceptions may be made.
As with all real estate, location matters. On the family beach, cabana #1 is closest to the restrooms, snorkel rental, and BBQ, though, as the only wheelchair-accessible cabana, it is usually reserved until all other cabanas are rented. Cabanas 2 through 17 are increasingly distant from the Pelican Bay facilities, but offer an increasing degree of seclusion. Cabanas 1 through 14 face the private beach reserved for cabana guests, while 15 through 17 face the breakwater and offer the most privacy. Cabanas 11 through 14 overlook the sand volleyball court, which may be a bonus or an annoyance, depending on your preferences. Cabana 10 was the first one built, and offers the "picture-perfect" view of your
Disney cruise ship, but we think cabana 9 probably offers the ideal combination of view, location and sun exposure
Over on the adult beach, cabanas 19 and 20 are set close together, with cabanas 18 and 21 a bit further apart. If you're looking for the most privacy, opt for #21. All of the cabanas on the adult beach are within easy walking distance of the Serenity Bay facilities, but the cabana hosts are also willing (in our case, eager) to offer a ride to and from your cabana upon request.
So what else do you get for your $400 or $500, along with some bottled water and a fruit bowl? Two words: Comfort and convenience. There's no racing to be the first off the boat to snag one of the all-too-few hammocks, or that ideal oceanfront sun lounger under an umbrella. You don't have to remember to pack the sunscreen or grab enough towels, and you don't have to seek a new shady spot throughout the day as the sun moves. You have a lovely space to store your belongings out of the sand and surf, your own personal space to rinse off and clean up after a swim, and a nice cool place to enjoy lunch, read a book or just watch the ocean. And far from what we expected, we didn't spend the entire day in the cabana. After we checked in, some hit the beach to sunbathe while others headed for Pelican Plunge or to snorkel. After lunch we enjoyed another swim, a bike ride around the island, or a lazy float in the ocean. The cabana wasn't so much our home as our home base, and it gave us all the flexibility to head off to other activities without worrying about saving our spot on the beach or carrying our gear around with us.

Looking better and better!!
