Just off Carnival Horizon 8 day that went to Grand Turk. We rented 2 cabanas at the Margaritaville pool. We were a party of 4 adults and 4 kids (ages 9, 11, 16 and 16). We requested, at desk on ship, that we have our 2 cabanas next to each other. We got off the ship and was at hostess stand at Margaritaville bar around 10:30. Hostess walked us out to our cabanas and they were not next to each other and she claimed they were last 2 left (though the 3 to the very right end did not appear to be occupied then).
We were told the server buzzer didn't work in 1 cabin. Hostess promised server would be around every 5 minutes...she wasn't. The cabin was dumpy and they need remodeling but the AC worked. We ordered food and drinks (the two 16 year old boys hung out in 1 cabin and the rest of us were in the other, on the deck). We all went to the beach for a bit (where, by the way, drinks are sold way cheaper by the locals). The water was dirty and rocky. Folks told us that when you get off ship and go to the right there really isn't a beach now due to hurricane. If you walk down toward Jacks, past the netted area, the water is a little cleaner and a little less rocky but still not fabulous (it is nice once you get past that shallow seaweedy rocky gunk).
When we walked back to our cabanas there was a lady laying on the lounger on the deck of one (the one the two 16 year olds were using). We asked our server to please shoo her off and she said "no, I am making tips off of her and you all aren't using it". We say "um...we paid a lot of money for that cabana". And she mumbles "you all are over here and I want her tip" and she walks away. Then when we get our tab ($400) and go to pay with CC, she says "can you pay my tips in cash so I don't have to share with the cooks and staff in the kitchen?". We tipped the cash.
Then...my DH leaves his sneakers in the cabana when we leave. We leave a good bit before the ship is due to go. But does the cash tipped server send the shoes to the ship? NOPE.
And Jack's shack has gotten more crowded too. I saw a pic from the day we were there and the whole beach area was packed like a sardine can with lounge chairs. We walked down there on our last cruise (the Magic in 2016) and was not super impressed. We were there with another ship that time and the island was packed. That time disappointed as well. My first time there was the best (on the Pride, only ship there, in 2013). I had a great visit that time. It wasn't too crowded and the water was super clean that I just sat at the water's edge and let the waves roll over me. It was soooo nice. But it's kinda jacked up now. Sad.
