Some prefer tower 3 as it is a little closer to the dock for the boat, some prefer tower 1 (I think) as you *may* get a view of Hulk, IOA.
If you do not care for dogs/cats....specify to be in the wing or area away from the pet friendly rooms...the resort handle this extremely well, but in case you are concerned. I t has been a while since we stayed so I ma not of much help, sorry! However, there may be a map of the resort in here somewhere...you could check it out and see if you have a preference and make a request on your ressies, but remember, it is just that, a request unless you pay for a specific view/upgrade. The grounds are beautiful, lush, wood work insode the resort is art in itself, so much more than just your room to see, have a great time!
