It depends on the forecast weather and the minimums the the particular
operator requires for ETOPS.  Most ETOPS operators only require the
"Adequate" airfields to be above landing minimas and not the higher
alternate minima.

An interesting aside, to operate into Easter Island, only one aircraft
can operate within it's PNR at one time.  That is, if one aircraft is
departing Easter Is. it must pass it's PNR before an aircraft
operating into Easter Island can pass it's PNR.  Just in case the
runway is blocked by one of them then the other would have nowhere to
go.
