The positives are spelled out in other reviews; no two cruisers will agree on everything.
If, for no other reasons than the size of the ship,the layout of the cabins, and the "extras" that you must pay for, I'll not do Epic again. There are many choices, after all. The "innovative" design is the biggest booboo sailing the seas (Sorry, Captain Vonner, for spilling the beans.)
I love the sea. I've enjoyed this cruise, and all of my cruises, even in lousy weather, even with missed ports, even when the food isn't all that great, even in a small cabin, even when staff is rude, even when the entertainment is so-so, even when the engine breaks down, even when my freighter is stuck high and dry on a sandbar on the Orinoco, even when I've had a bad fall and had to stay in the cabin for seven of ten days--all of which I've experienced--but I'll choose another ship next time, rather than the Epic.
The layout has you walking right through the middle of a bathroom that should have been to one side, in one piece, as on other ships. A sliding door to the toilet, that can slide open in rough seas,is not appropriate. Yes, the toilet set-up is as bad as you might imagine. Stepping directly from the shower or tub on to the wood floor of the foyer is far from private. The bottom of the tub was smooth and slippery, while the toilet area had a non-skid surface. The designer's brains must have been stirred into his oatmeal. A month in dry-dock for re-arranging the bathroom (cabin door on the side, rather than middle) is what this ship needs. Too late to do anything about the chintzy atrium.
I had reserved an inside cabin just a few days before sailing, but awakened with a scratchy, dry throat and had to upgrade to a balcony because there are no mid-range ocean-view cabins. If guys who design ships can put this huge floating monstrosity together so that it doesn't sink, why in the world can't they fix it so a humidifier can keep the passengers from dying of Sahara-like dryness?
The movie screen is immense, but I'd like to see a real (dark) movie theater rather than an open, well-lit lounge in the high traffic atrium.
The captain is a delight.
