As mentioned, a regular party is fine for dealing with these, as long as you have a MP refresher.

One thing to note on these doors: they can be disabled by a Thief, which keeps the Gargoyle from popping at all. If you have a Thief (and don't mind spending money on items to save time), using Skeleton Keys to disable these can result in the vast majority of the doors being successfully disabled.

You'll still have to fight the occasional mob inside the rooms, but it goes much faster than if you don't disable the doors.
