Timing is key. If the museum is not of interest, church only, Sunday prior to Mass might be good
As of right now, it's $9.50 for adults, $7 for seniors, and $5 for children ages 7 and up. Free for kids 6 and under. However, if you go on a weekend when they are having a wedding, it's $5 or $5.50 for adults. The downside is you may not to get to see the inside of the mission chapel itself.
