Thanks all for your advices ,the "BEACHSIDE SUITES" were on the "famous list" as well, AMB cert yes, but upgrades no. So I went for the "PREMIUM CLUB LOUNGE ACCESS OCEAN VIEW ROOM" got a confirmed upgrade to a "LAGOON VILLA CLUB LOUNGE ACCESS".
They looks pretty nice as well, and already earned the 200 $ fee for the IC Amb :-)
