As you've noted "it depends". A 30 second relocation doesn't bother me, but a 30 second quiesce time does. For Very Large Guests, it's typically better to use application clusters so that you don't need to move the guests. Just take one down and let the other members take the load. E.g. I wouldn't use LGR on an Oracle db, given it's failover capabilities. Let the standby Oracle instance take over.
