Not sure how helpful this is but there are also several hotels in Brooklyn Center near the I-94/694 interchange. At least one of them - Country Inn and Suites - will have the sofa bed with separate master suite, etc. These might be a few miles farther than Roseville/Woodbury and on the “Minneapolis” side of the Twin Cities rather than St. Paul. But they might serve as a backup. there is also an Embassy Suites in that area.
