There are very few rooms that are actually ocean front at the Marriott, but I believe that you can see the ocean from all rooms. We stayed at the Marriott Ocean twice, are platinum premier and timeshare owners, the first room they gave us on first visit was the WORST room in the place, near road overlooking ac units, we complained and got a little better room. Second visit we were ocean front by tipping. I would not count on the upgrade in Aruba.
If you want that view i would book it. They are mostly full in july. When you get there ask to get this room #767 I have been going to aruba since 2004 and i own at the surf club. This is the best room besides the Governor suites that are in the front of the hotel.
If they do not have that room ask the same spot where that is but lower. You will get a view of all of palm beach and the pool
It is also a bigger room than some of the others.
I noticed you are going to Aruba this summer - we just went there last winter.
Be aware of two things:
1. When you dine outside in the evening, the wind really kicks up sand and we were not happy with our elegant meal at the Surf Club on the beach due to the wind. My salad plate blew off the table, too. But it is BEAUTIFUL at night, definitely have a drink on the beach or just sit there and take in the sunset.
2. Forget about snorkeling in Aruba. The tourism has killed all the reefs, there are few fish and it's quite a disaster. We were massively disappointed in the snorkeling excursions we took.
3. While you're there, check out the Aloe Factory Tour (free). It was really interesting, and we loved the whole experience.
I had a side view room there in 2009, and it wasn't bad. I don't think I was Platinum then so I did not get any upgrades. I wouldn't expect an upgraded room in the busy season, though. In Cancun last year in the off season with an obviously near empty hotel I was not given an upgraded (larger, suite, etc.) room with my platinum status, only one with a nice view,
