? Sandals St. Lucian Grande vs. Sandals Antigua

My wife and I are looking to travel to either Sandals St. Lucian
Grande or Sandals Antigua in June 2004.  We would like some feedback
or recommendations on which may be our best option.  We stayed at
Sandals Halcyon in St. Lucia a few years ago and loved it... but the
new Grande looks even better.  Does Antigua or St. Lucia have better
weather in the middle of June?  Any help would be appreciated.
