Mother's Day 2015

We’re traveling to WDW for a week around Mother’s Day 2015, and I was thinking of visiting Universal for the Harry Potter attractions and areas on that Sunday (Mother’s Day). Both parks look really low on the crowd calendar, which seems… odd to me. When I checked the Universal site, the express pass was not available that day, so I assume it sold out? What is the feasibility of coming from off-park, being there at rope drop, and being able to ride Gringott’s any time that day with a <30 minute wait?

Thanks!

10th may all express tickets are showing for me . Possibly change your browser $65 for park to park standard which is cheapish so they don’t expect to be that busy.
