Help - plan to make birthday cakes Friday and have no cake containers

[extremelychocolateymilkroll]

Dd's birthday party is Saturday and I plan to make 3 cakes the day before which I will ice on Saturday morning. Have just realised I don't have any cake containers. Where can I get some or failing that could I just cover them in foil? I'm making eggless choc cake TIA

When I run out of containers for cakes/buns I usually put them on a plate or in a roasting dish and cover with two layers of cling film and leave them somewhere cool. They're usually fine for 2-3 days (assuming they aren't eaten before then)
