Paradise by Sirene is the new, adults-only sanctuary at JW Marriott Marco Island. It’s essentially a “resort within a resort,” open to guests age 16 year and over, and it’s equipped with a private infinity pool, adults-only bar and restaurant, private gym and incredibly spacious suites with sweeping views of the Atlantic.
This intimate sanctuary is still within the JW Marriott Marco Island resort complex, but it’s completely removed in its own tower (Lanai Tower).
My friend Jason and I checked in for three nights to see why everyone was raving about the slice of paradise in Florida. Honestly, I was speechless.
Here’s my review of Paradise by Sirene at JW Marriott Marco Island.
JW Marriott Marco Island Resort is located in Marco Island, about 40 minutes from Naples, Florida, and about 50 minutes from the airport in Fort Meyer. 
Once you arrive, you’ll swing left to the private check-in desk reserved exclusively for Paradise by Sirene guests.
The resort is directly on the beach. The building to the right is the Paradise by Sirene Lanai tower. No kids!
Who doesn’t like big, spacious suites? My corner suite came with a massive living area with wrap-around balcony and unobstructed views of the beach and ocean. 
Most of the 94 guestrooms at Paradise By Sirene have amazing beachfront, pool or resort views.
My suite overlooked the adult infinity pool, as well as the entire coastline.
Paradise by Sirene guests will have incredible sunsets enjoyed right on your balcony.
Paradise by Sirene guests enjoy access to an intimate, private infinity pool reserved for anyone checking in. Remember, it’s adults-only at Paradise by Sirene: you won’t find any kids at the pool.
The pool has incredible views overlooking the beach, as well as the main resort complex.
You don’t have to go far for service at the pool.
We loved the pool bites, like lobster rolls and guacamole, and it came fast and well presented.
Guests of Paradise by Sirene also receive a private, exclusive area right on the beach that’s mere steps from the resort.
The private beach area is quiet (again, away from any families or kids), which we appreciated. 
The Paradise by Sirene beach area within JW Marriott Marco Island Resort also came with a private beach butler. You can order whatever you like!
Guests of Paradise by Sirene have another perk: an exclusive restaurant. Tesoro is a bar, lounge and restaurant open for breakfast and dinner.
Tesoro offers complimentary breakfast, which includes made-to-order hot food, like eggs and pancakes, for all Paradise by Sirene guests.
The restaurant is beautiful, and has direct ocean views.
But I loved my balcony view so much, I ordered breakfast-in-bed most of the time.
I should mention that while Paradise By Sirene has a private gym exclusive for guests staying here, the spa is part of the main resort complex. It’s gorgeous, and it has a mens and womens facility with respective steam room, sauna, whirlpool and cold plunge pool.

Sweeping views of the Atlantic? Must have quite an observation tower, as the JW on on the Gulf, not the Atlantic.
