When I went last June, the posted wait time was 30 minutes in the early afternoon but we walked right on. (It may be that it has been shut down and just opened up again). However, having experienced it, my husband and I agreed we would have been angry had we actually waited half an hour for that (without children). Disney has touted the advanced animatronics on this ride but, overall, I found it to be less dynamic than any of the dark rides that existed on opening day and not worth a lengthy wait. Have you seen the digital rendering of the ride that's included as a special feature on the Little Mermaid dvd release from a few years ago? That is FAR more exciting than the reality.
