Despite being the cheapest option, the Britannia accommodations have high-end amenities like sparkling wine, Penhaligon toiletries, and tea and coffee machines.
That's nothing compared to the most luxurious Queens Grill suites, where guests get amenities like pillow menus, stocked mini-bars, a butler, fruit, and pre-dinner canapes.
Forget the sparkling wine — Queens Grill travelers get a bottle of Champagne.
