Clogged septic tank on a sunday-what are my options/ obligations?

[Steve S.]

I can’t find someone yet to come pump it in a Sunday. The toilets and showers are unusable and the family has some kids. 

1) what are my options?

2) am I obligated to put them in a hotel until tomorrow when someone should be able to come pump it?

3) there was no warning from them of any issues and no big rain. This is surprising it happened all the sudden

Thoughts / suggestions?  This town is not right by a major metroplex so may not have any Sunday options
