Bachelor party Medellín, with the party built into the ride.
Keep the crew together. Turn the chiva into the main event. Add professional performers instead of making the pole an awkward group prop.

Make the chiva the part everyone remembers.
A bachelor weekend can turn into twelve unrelated reservations fast. The bus solves a specific part of the night: the crew stays together, the ride is part of the party, and the entertainment comes to the group instead of becoming another venue change.
Build the night around one moving venue.
Pickup, music, drinks and the show happen inside the same experience. Where you go before or after is up to the group.
Hotel / Airbnb meetup
Get everybody in one place and confirm the pickup point with the operator.
Private chiva + show
The ride itself becomes the centerpiece rather than dead travel time between venues.
Continue the night
Coordinate a drop-off that works for whatever your group is doing next, subject to the operator's route.
What should the organizer have ready?
You do not need a minute-by-minute itinerary. You do need a reasonably firm date, a realistic headcount, a pickup area and a contact person who will actually answer WhatsApp. If the group has a strong performer preference or needs multiple performers, say that up front because it affects availability.
Should you publish the whole plan in the group chat?
Probably not. The organizer can handle the booking while the rest of the group just gets the meetup time. If the groom is meant to be surprised, put that in the notes so the conversation does not accidentally spoil it.
What about photos?
Your group can take normal party photos, but performer privacy matters. Ask before filming or posting a performer. Specific rules can vary by performer and operator, so confirm them as part of the final booking details.
Send the date before someone books another van.
One request tells us the group size, timing and show preference.
