I am online checkig into prices for a friend who wants to take her kids to WDW this spring. They are considering the ASMu family suites as an option. She's also considering a trip of 7 - 10 days, depending on cost. I found availability in May for the suites for 8 nights. But if I drop one night in order to see the difference in price for 7 nights, then the suite doesn't show as available. If I can book it for 8 nights starting on one night, why is it showing as unavailable to book for 7 nights starting 1 day later? That makes no sense to me.
