If you stay at the Hyatts you need to drive to the main street and parking is a bit of a hassle.
Sorry, but that's just not accurate for Hyatt Sunset Harbor re: "you need to drive". It's true only for the other two Hyatt timeshares in Key West (Beach House and Windward Pointe). Hyatt Sunset Harbor couldn't possibly be better located; no need to drive from there
at all, actually.
But to the OP inquiry on recommendations, we like Hyatt Sunset Harbor best (although it's an old property) and The Banyan. Don't really know much about Coconut Beach Resort, but would like to stay there sometime. No knock on the Galleon, whose praises people routinely sing, but it just somehow doesn't float our boat (...no pun intended, with the boat slips being there and all). Frankly, I think Galleon's "popularity" stems in large part from the simple fact that it is apparently the
one and only RCI-affiliated timeshare property anywhere in Key West.
We owned at Coconut Mallory for a few years. Can't recommend it for location, staff, upkeep --- or for anything else, for that matter. Avoid it.
What's tough in Key West is of course availability. I can't think of any other place where the laws of supply and demand are more evident.
As a relevant aside, we've been chased out of Key West
twice during "hurricane season" in evacuations over the years and will frankly never risk going there again during that time frame. For us, it's just too distant and too expensive a place in terms of travel time and effort and lodging cost to risk getting run out of Dodge (...again) on such very short notice. Felt "short changed" --- but "short changed" in KW is "big dollars".
