If you've tried this in his failed... Or if you tried this and it's worked... Let me know

I'm going to be out of town this evening with a hotel to myself in a city full of young sexy thangs, and have been using bumble in said town to line some things up.

So far I have (what appears to be) an HB8 and an HB9 down for drinks a block away from my hotel. I have the HB9 down for 7pm. I was thinking of scheduling the HB8 at 9pm... And then cancelling if things go well with option #1

What are my chances of the HB8 showing up early? Anyone tried this and had it backfire. What went wrong. Thanks.
