App meets before or organic?

Headed on a trip next month and have a few free nights before a wedding. We’re both attractive in our 20s.

Already discussed being open to the chance for her to play with another guy, whether that be MFM (us and another) or just the two of them.

She’s down to meet organically but since we have a short window we’re curious if we should look on apps ahead of time.

Shouldn’t be too hard to find a guy organically I’m thinking? It’s a place with lots of bars, casinos and people there for a good time

any advice or experienced appreciated.
