The upgrades include all staterooms and suites, dining, spa and entertainment.
'Each corner of the ships will have a new look and feel, setting a brighter, more contemporary ambience, while the new venues will bring guests fresh experiences,' Azamara president and ceo Larry Pimentel said.
'We're also investing in new on-board innovations and have paid close attention to the smallest of details. We really are redefining our on-board experience in every way,' Pimentel added.
Azamara Journey will enter drydock in January in the Bahamas, while Azamara Quest will undergo its work in April in Singapore.
Early this year, Seatrade Cruise News first reported the plan for these major dockings.
