Losing their home and wearing out their welcome with friends, a married couple devise a plan to become temporary residents at a hotel

Think about challenge ? for example: they want stay for free in those hotels. This is a conflict (they vs. staff) and driver for your plot.

think "wearing out their welcome with friends" is unnecessary.

Change temporary to permanent (even if you know it's temporary) that may setup the conflict for your idea and the logline a bit easier. Also what richiev says works as well.
