AKL is one of my favorite resorts.
To answer some of your specfic questions:
"what are the rooms like?" - if you are familiar with the rooms at WL, they are identical (except for the style). Many rooms overlook various savannahs, if you can swing the expense of a savannah room it's worth it. I think every room now comes with a refrigerator (at least mine did a few months back). Each room has a balcony. Most come with 2 queen beds, a few rooms have bunk beds.
"is it far from other parks?" - its about 5 minutes by bus to AK; about 10-15 to the other parks. Bus service is great. AKL has its own bus (as opposed to sharing with another resort) and there is only 1 stop. I don't find the perceived remote location to be a problem, but it is for some.
"how is the pool?" - the pool is big, nothing fancy. It has a zero-entry area and a small slide. The bottom is painted so the pool water looks grey-ish green.
"is there a hot tub?" - yes, there are two.
AKL has 3 restaurants. Boma, a buffet is especially popular and is one of my favorite places in WDW.
The hotel is magnificent, especially the savannahs and the lobby area. The hotel also has lots of activities throughout the day.
It is a wonderful hotel - I hope you enjoy your stay.
