Pick up points and Hotel room Fun.

As the pandemic stats to end, I?ll soon be traveling - Monday through Thursday. By the way I am a total bottom, that is yet to find a nice top to get fucked with on a business trip.
In the past, I posted on Doublelist, but found only ?Undesirable? folks, based on how they responded, their language and my gut instinct. So I never invited them to my hotel room.

i hear that some here have had sex with folks they have found in the bars of their hotels. I realise that there is no magical formula, but is there a technique to follow to be successful in picking up someone? Are there cues to watch for? Are there any ?Do?s and Dont?s?. Would really appreciate learning these points.
Are there any downsides to doing this in a hotel.. being a closeted bottom?

I guess I should keep lube and condoms ready, if ?rear entry? happens.
