No sync subscriptions

I have a 70 GB merge-replicated production database on which I need to
perform some maintenance. This maintenance will require the removal of my
subscription. I am trying to minimize downtime, obviously, and wonder about
the ramifications, if any, of setting up a no-sync subscription after my
maintenance is complete. The subscription exists off-site, and I want to
avoid a new subscription push across the WAN. Also, I see a snapshot option
to "Keep the existing table unchanged." Would that be better than a no-sync?
In the past, we have always dropped and recreated objects during replication
setup.
Thanks!

Stephanie,
the no-sync option is the way to go. "Keep the existing table unchanged."
is used for a central subscriber topology. The only thing to be wary of is
making sure the data stays synchronized ie can youprevent changes to the
publisher during the subscriber downtime?
