IMO ...

these 5-day rentals frustrate the heck out of me.

why not make them 5 day rentals. To be honest, 5 "days" worth of rentals costs more than a single 5-day rental typically.

ugh ... i just never rent 5 days at a time.

if i do, i'm on holiday and that means, i'll use Hotwire to save a ton of $$.

oh well ... another vent i guess.
