I can't recall ever finding an EL at a Marriott resort, though I may be forgetting something, and I've been to most every Marriott in the Caribbean and Hawaii (yes, I know it's not out of the county...).

I've also been upgraded to ocean views, suites, etc. at almost every one - St. Kitts, Aruba, JW Oahu, Wailea, Grand Cayman, St. Thomas, Waikoloa, Kauai - actually, every one, based on my PLT status. I've never booked more than a Garden View.

Hmm, just noted you also have been to all the Caribbeans and Hawaii, and want a flight of less than 8 hours from California. There may be a resort in Canada than I'm missing, but you may be out of luck. (Costa Rica is just outside your range - don't recall an EL there either)
