Princess Cruises’ 3,092-passenger Emerald Princess was the largest ship of her kind when she launched in 2007, but now her size feels downright manageable. Onboard, recent refurbishments mean you’ll find a mix of old and new: Modern touches include flat-screen TVs as well as Wi-Fi, although dropped signals are a common passenger complaint. A late 2015 dry dock added a host of new features, including the Salty Dog Gastropub and SHARE, Curtis Stone’s first restaurant at sea, where diners can share plates of fresh charcuterie and buttered lobster at communal tables.
