I'll be staying here in March. The post from SkiAdcock about Golds/Plats having access to the lounge is encouraging.
I read the reviews on the Marriott site and filtered by Gold status. It seems everyone who mentioned the lounge in their review said they received access automatically apart from one guy who said he had to 'battle' for it.
If anyone else has info to share about this property I'd be grateful. If I couldn't get lounge access I'd probably switch to the HIX nearby to get breakfast included.
