What happens when the paths of three couples, each with a different plan for a long weekend in Melbourne, collide? Absolute mayhem, as you will find out in Centrepoint's latest production - and you won't stop laughing.
Meet Lizzy and Noeline from Rongotea who are intent on a week of intense retail therapy in the fashion capital of Australia.
Then there's the boys, rugby mad Boxer and Swanney, who are in the city for the Bledisloe Cup.
Throw in fussy academic Clifford and his anxious wife Rose, off to a conference where Clifford will deliver a keynote speech, and see what happens.
It's a busy weekend in Melbourne and the hotels are packed, as Lizzy and Noeline soon discover when they try to check into the YWCA. Their booking has gone astray and there's no room at the inn.
"This wouldn't happen in Rongotea," proclaims Noeline.
The boys have better luck at their serviced apartment, but their mates haven't turned up to join them.
A chance encounter with the girls when Boxer is off on a beer run and our knight in tarnished armour soon has himself a couple of extra room-mates - one of them extremely drunk.
Clifford and Rose are not so lucky - a mix-up by a harassed hotel employee sees them sent to the same room.
Then follows the funniest scene I have ever seen in live theatre as the paths of all six collide, cleverly choreographed and brilliantly executed by the six actors. The audience was in stitches.
The shopping scene in the second half was equally clever as the girls and Rose vie for the best bargains in a lingerie shop.
It's a great cast, well experienced in comedy roles.
Levin's Darlene Mohekey is Lizzy, whose big personality shines through and best friend Noeline (Lyndee Jane Rutherford) only catches up when she's had five or six too many.
Craig Geenty as Boxer the Boozer is loud, rude and crude (love his jokes) and best friend Swanney from Foxton (Andrew Ford), the shy divorcee, knows exactly how to control his rugby-mad mate - crouch, touch, settle.
Their much older room-mates are delightfully played by Centrepoint veterans Peter Hawes and Helen Moulder. Clifford is the original grumpy old man - he fancied an outing to Les Miserables rather than Mary Poppins - and he leaves his wife to do everything, including carry their luggage.
They are ably supported by newcomer Jared Kirkwood, who plays everybody else, eight other bit-parts from a hotel receptionist and waiter to a child in the toy department and a boney-kneed woman shopping for undies.
It's a complicated set for a Centrepoint production with half a dozen neatly planned and executed changes.
Shop 'Til You Drop was written by Alison Quigan and Ross Gumbley to make the audience have as much fun as they do. They succeeded.
