Personally, I wish I could go in April, May, Sept, Oct or early November. It's very hot in the summer though still great. Only 3 more years until I can vacation while you're kids are in school though I'll then have 2 in college and may not be able to afford to go. I've stayed at GO and own there, I've toured Barony twice, had 2 concurrent weeks at Monarch and stayed at
DVC-HH. I've also stayed at Marriott's Harbour Pointe where I also own and is on the other side of Shelter cove from DVC.
My personal feelings are that I'd rate GO, Barony then DVC from a resort standpoint. From a location standpoint, I'd rate Monarch, GO, Harbour Club, Barony, Swallowtail, Spicebush. I'd put Harbour Pointe, Sunset Pointe, DVC as not as good locations as the rest (and many others on HH) though not in bad locations. Resort Quality compared to location, I'd rate as GO, Monarch, Barony, DVC. All are great resorts and none are in bad locations.
