Small fleet only 4 ships, small ships only 700 pax, big on inclusions.
 
A signature of Azamara itineraries is that they always try to stay longer in ports, often with an overnight stay. This is a huge point of difference in small ports like Dubrovnik or Santorini, which can be overrun if many ships are in port. All other operators will require everyone back onboard by 5 or 6 pm. If you are on Azamara you can stay ashore and enjoy these iconic locations without the crowds. This is a big plus.
 
Azamara offers really great itineraries with a heavy focus on the Med, Greek Islands, and Croatia. 
Any voyage that sails to or from Venice will invariably include Croatia and Dubrovnik, which are some of the most sought-after itineraries in the industry. And being a smaller ship it is easier to get on and off the ship in tender ports.
 
Standard beer/wine/ basic spirits included
Gratuities paid
White Nights - Signature Party on deck 
Signature cultural events ashore on select itineraries
Taxes are additional
 
Bigger bang for your buck
As they include standard drinks and tips, which run at an approximate cost of $100 per day on other mid-range lines, they are $700-1000 better value on 7 and 10-day voyages.
 
Cabin selection notes/tips
Inside - same size as other cabins without the balcony
Ocean view - avoid Category 8 which are obscured cabins, these can be almost totally obscured by lifeboats.
Avoid Ocean View Guarantee cabins as you will end up with cabins no one else wants, and these will invariably be Category 8, Obscured.
Balcony - V3, V2, V1 - standard balcony cabins, all the same size and all but identical.
There are no obscured balcony cabins
V3 will be forward, aft, on lower decks, or under restaurants, close to lift lobbies.
V2 will be better positioned, mid-ship and on higher decks than
V1 will have the best position, but again are exactly the same.
 
Plus Cabins
These are all exactly the same size as V3, V2, V1 cabins.
These are priced higher as they have better positions again, more central and higher.
PLUS cabins get significant additional perks that include:
Complimentary in-room spirits
Complimentary Internet (120 minutes or 25% off the unlimited Internet package) per guest
One free bag of laundry service per stateroom, every seven days
One night of complimentary specialty dining for two, every seven days
Priority embarkation and debarkation
 
The best PLUS cabins are the aft-facing V1 cabins, as these look out over the wake.
Avoid V1 cabins that look out over the bow as these have a closed metal instead of glass balcony railing.
Also, these cabins suffer from significant early morning noise due to dropping the anchor in tender ports.
 
Suites
These get additional perks:
$300 OBC
Butler
In-suite afternoon tea
 
But the biggest advantage is these are wider and have larger footprints and hence the bathrooms are much bigger than standard cabins, which have very small cabins and shower curtains, that cause some consternation, but seriously you are only in your shower a few minutes a day.
 
Spa Suites
There are not many of these onboard, but if your budget stretches this far they are absolutely worth it as the layout with the bathroom having a huge window is one of the best floor plans at sea.
 
Entertainment
Being a small ship entertainment is limited, however as they run very port intensive with late night or overnight stays, I'd rather be ashore in Dubrovnik and Santorini than watching a show onboard.
 
Specialty restaurants
There are two, at a small additional charge of about $50
Aqualina - Italian
Prime C - Steak House
 
These are great but if your budget is tight then the food in the main dining room, the deck grill, and the buffet is really great and you won't feel you are missing out.
 
They also run a chef's table which is about $99 per person.
 
Afternoon Tea
A nice surprise and something over looked by many.
