I haven't read all the posts on here so I dont' know if anyone else has suggested this, but park at the Royal Pacific lot, head through the hotel out to their water taxi and take the boat in. It saves you a lot on walking but you will have to wait for the boat. That's what I have done before. I was actually staying at the RP, but then left to go to the beach, got bored in a day or 2 on the beach and came back and just parked in the RP lot, it worked fine then, that was last year.
