If you're open to condos, Orlando Sunshine is right over I-4 from Universal Studios. All they have is 2 BR, but they're reasonably priced compared to hotel suites, at least the times I've done comparisons (we go off season). Then everyone would have more privacy and you'd have your own kitchen.
However it's a Timeshare so only once-a-week housekeeping unless you pay extra. Very small resort with a pretty basic pool, but OTOH the units are large and were just refurbished this past year, so should be in great shape.
