We are sure the Key Largo Bay Marriott Beach Resort was a nice Marriott when it was built and first opened in the last 1980s or early 1990s. But the whole hotel feels outdated with only lipstick on a pig updates since its opening. We felt like we were taken back to 1998. Kind of like walking into an old shopping mall that hasn't been floor-to-ceiling renovated since the 90s.
It was very difficult when booking to know what has and hasn't been updated because the pictures vary, including showing rooms with carpet. Who puts carpet in a guest room at a beach resort with sand?
Anyways, we stayed for 1 night on a road trip in Florida. For reference my husband is Bonvoy Lifetime Titaniums after a career of travel. We've stayed at hundreds of hotels and resorts from every brand.
For about $400 for a weeknight before high season, this is no where worth it. You can stay at a much nicer independent hotel or even a Ritz-Carlton at that price point if you shop around. The Key Largo Bay Marriott Beach Resort is a very tired hotel that shouldn't be a Marriott. Maybe a Delta or Four Points or even Courtyard. But the rooms are tired despite some newer furniture, the food and beverage is basic and not high quality, and the execution of hotel services (let alone the attention to detail) is lacking and not anywhere near a 4-star or 5-star standard.
Zero recognition as Lifetime Titanium; not even a voucher for free parking. Took the points over breakfast.
