Best way to ride Gringotts with minimal waits?

[davedmaine]

We'll be at Universal all next week, staying at the Royal Pacific. What's the best strategy for getting onto Gringott's these days? We'll have six days to try to manage it, but my husband doesn't like waiting more than 30 minutes in line for anything. I can drag him and the teenagers out of bed as early as necessary. Advice?

We went yesterday morning around 11 am. Posted wait time was 90 minutes. Took us exactly 70 and we were on the ride..
