I love my trolley, wouldn't be without it. I only came to the party about 6 years ago after years of regularly juggling trays and dishes in one small single oven, catering for up to 15, and swearing like a trooper about it every time. I should have got it years ago! I haven't a lot of spare room, but it sits in the hall, full of all the china/cutlery I only need when the hordes family descend.
Alea, a friend offered me a "spare" trolley last week. She's got three and thinks she can probably manage with just two now.
