First visit to orchid show - what to expect?

[Dimples]

Hi all,
The San Diego County Orchid Society spring show is next month, and I plan to go. Partly to learn more about orchids, see plants in person, and also to buy a few things if the opportunity arises.

I've never been to a show before and wanted to know what suggestions more experienced members have on topics like:

Multi-day shows - what day is "best" to go and why?
I can imagine the days have different vibes. Maybe all of the super-serious collectors go on the first day to score the pick of the litter plants, middle days are general audiences, and bargain hunters show up on the last day? What have you noticed?

Show etiquette - anything newbies need to know aside from the obvious of look with your eyes (unless you plan to buy something), you break it, you buy it, and the like?
Will vendors be upset if you carefully pop a plant out of the pot to check the roots? Should you ask them to do it for you? What about haggling/price negotiating? Is it an accepted practice, or is it frowned upon? Anything specific to orchid shows that would be helpful for new people to know in advance?

Logistical tactics - what's your method for visiting a show?
Do you scope out all the vendors/displays first before buying anything, or are you a buy it when you see it type of shopper? How do you carry/transport purchases while still at the show (is there a lounge/waiting area for all of the SOs that get dragged along to babysit the plant purchases while we run back in for more? haha)? Bags? Trays? Do you run each purchase out to the climate-controlled cooler you have waiting in your car?

I'd love to hear your thoughts and suggestions, even if it's as simple as "go when it's convenient and enjoy yourself," but any insights would be very appreciated.

Thanks!
