Just spent a week at Domes Miramare Corfu as Titanium. Upgraded on nights 1+2 (Emerald Suite Sea View on the upper floor), standard room 3-7 (Emerald retreat also on the upper floor). Likely no connection and just coincidence, but first 2 nights were booked with 35K certs, and the final 5 on points (5th night free). Hotel was at or near full capacity, but never felt crowded. Obviously, we took the daily breakfast.

Some insights:
Reach out to the hotel for their menus and the concierge's email as soon as possible if you have not done so already. Several emails to the concierge (from weeks to days before arrival) went unanswered. IME you'll need to be persistent.

Book Spa and Dining as soon as possible, before you arrive if you can. They've implemented an online booking process for these, but more than once, they had no record of reservations we had made and other times the site just simply did not allow for booking. Showing up at 10:30 pm for dinner and being told they can't accommodate you isn't fun. At the same time, local dining was a spectacular experience during every single meal.

I've seen much discussion (both here on FT and other sites) focused on this being a "Luxury Collection Resort" property and not living up to whatever arbitrary distinction folks associate with this label/sub-brand. However, too many of those posters and comments failed to incorporate context into their considerations. For the region, country, island, and local area, this is, by any comparison a luxury property. This becomes immediately and abundantly clear as you explore beyond the resort in Moraitika and neighboring Messonghi. And, that's not to say this property is better, or that any luxury resort experience is superlative to less expensive or more accessible competitors — it's just noticeably different. I prepped my SO with the following statement: "This isn't Domes of Elounda."

All in all, this was an incredible value for a 35K/Night Marriott Property and we'd return without question.
