Too late for the party but just setting it on carpet pad - not the thick foam but the thin basket weave non skid stuff - would hold it in place effectively certainly for a short term. Corian is not as heavy as stone but I have used this method for many years for a stone top. We have a 3' square x 3/4" thick granite top that we simply set on a plywood top table each summer on a few strips of the pad. Never moves until I put things away in the fall.
