Pros
Vestiges of what it was like pre-I P O. There are fossil records that show how awesome it used be to work for HA. One old survivor is the vacation time (which is phenomenal by most standards.) However, all the good qualities that once were or no more thanks to the I P O bug.
Cons
I P O disease. Look it up - what happened here is textbook. I worked here pre I P O and for quite a while afterwards. I saw and experienced the shift. Think about it - HA sells vacation rental ads. That's all it does. They can have some fun with that and keep it to scale. However, the big C's decided to go 100% corporate on everyone, including the customers. Be very aware before applying here. Take the offer only if they offer you an exceedingly nice package (normal employees get no 401k matching, measly health insurance, and sub-par management.)
