Aliens on Vacation

David isn't happy about leaving Florida and his friends to summer with his crazy grandmother in &quot;Middle-of-Nowhere,&quot; Washington. Arriving at her Intergalactic Bed &amp; Breakfast, he isn't surprised by its the-60's-meets-Star-Wars d cor, but he <i>is</i> surprised by the weird-looking guests. It turns out that each room in the inn is an off-earth portal and his grandma the gate-keeper, allowing aliens to vacation on Earth. Grandma desperately needs David's help monitoring the visitors, shopping for cartloads of aluminum-foil for dinner, and taking rambunctious alien kids, that glow-in-the-dark and look like trees, camping. The problem is, the town sheriff, already suspicious about Granny, is a scout leader camping in the same spot. Will David blow Granny's cover, forcing the B&amp;B to shut down for good, or will the intergalactic police have to intervene?
