I think it all depends on one's tolerance for uncomfortable conditions. As live aboards you already have a higher level of that than most but boatyard life can be trying. Some yards are fairly pleasant and try to accommodate cruiser/live aboards. Others, not so much.
In twenty years of living aboard, including one stay in the yard that lasted a full FIVE MONTHS
, we have only resorted to a hotel once; when we painted the boat and had the hatches off.
