I think I have a co-worker who stayed at the Liki Tiki a couple years ago, so I might be able to ask them their opinion. i think I remember hearing that their big attraction was a largish pool/water play area.
Which Celebrity resort are you looking at? they have a couple in the area (resort world plus one off Palm Parkway). i stayed at the one off Palm Parkway and my brother owns at Resort World.
It might also help to know what you are looking for in the resort and party size. (crash space? resort ammenities? large group? small group? kids? etc)
