Okay, let’s keep it simple, as finite details can be found on the web and critiques can be subjective. If one had a choice between only these two, then it would be BJ, in an instant.
Not that Rendezvous I’d bad or worse, It’s just Rendezvous has too much of the “seen it before”, been there done that many time before. But BJ offers more of the warm feeling one is actually in St Lucia. Also, the BJ food is different in a more St Lucian way, with Rendezvous being more towards the American tastes. Also, a previous poster mentioned, buffet manners of some day passers in R are to be questioned.
Both have great pools, but R’s beach is on one of the most popular and busy beaches.
Experience? One should not miss spending time and talking with St Lucian people, in addition enjoying the sights, sounds and their hospitality. It’s then one will understand the magic of this beautiful island.
PS. Chairman’s Reserve Spiced Rum should not be missed. Although reasonably priced, it’s actually very good.
Whatever, one chooses, enjoy the island and it’s people.
