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.
Not that anyone is listening:
Hey Captain Vonner!
No complaints about our cabin except the above. And the fact that it had excellent storage for all the clothes that crazy passengers drag on ships, but not enough space for big/fat people!
See review, please.
