Diamond club tickets!

Want to take my current fiancé (we will be wed 3 days prior to the June 1st game). I am hoping to surprise her as this would be her first ever baseball game and trip to Houston (My hometown).

What are the chances of scoring 3 diamond club tickets on the secondary market or just in general?

I know price can be steep (if available) but willing to pay the piper being that this will be just after our wedding and a special weekend for us.

I have tried searching online and can’t seem to find any. I also joined some FB groups and have my fingers crossed.

Any suggestions are greatly appreciated. I am also open to other seats options that leave a memorable and lasting impression?
