I STRONGLY recommend you do NOT go into public at all. That means no beach and no movies. I do recommend being in nature if possible as it is the ideal situation to trip in. You live in LA so it might be hard to get to nature that doesn't have other people, but if you can manage, please do yourself a favor and do it.

Maybe someone's back yard if it's private.
The main thing is to avoid stressful situations. Set and setting are of utmost important.
Set refers to mental set and this means you need to go into it with a positive mindset, wityhout anything subconsciously bothering you. Make sure you don't have other responsibilities that might stress you out, or that you're not hiding something from yourself.
Setting refers to the circumstances in the external world you put yourself in. This is VERY important so please do yourselves a favor and don't ignore this part. Make sure you're alone with just the people you're tripping with. Being around people not in your group will almost surely cause anxiety and is a great way to make a trip frightening and unpleasant. Make sure you only trip with people you truly trust and are close to. If there is weirdness between anyone, it will come out during the trip for sure. Make sure you do not have any responsibilities that will come up during the trip. Make sure you will not need to appear like you're not tripping to others at any time during the trip. Turn off your phones.
Above all, remember to go with the flow. Try not to have any expectations because it will be different than you thought, for 100% sure. If you become panicked during the come-up, remember that it's just a drug and you'll come down. You did NOT go insane and yes, you WILL be okay. Sometimes the come-up can be overwhelming because it's fast and a huge transition from sobriety to tripping. It can feel like you're poisoned, like you're going insane and never going to be right again, and that you're a piece of shit druggie. If this happens, it will pass once the come-up is done. Try to remember that if you power through it and don't give in to the negative feelings, once the peak hits you'll be swept away in the glorious mushroom state and feel amazing. You just have to get past that come-up, that transition into the realm of psychedelics.
And you may never get these difficult parts of the trip. But in case you do, keep what I say in mind.
Good luck! And happy tripping.
Also, watching a movie is a waste of your trip. Movie watching is not what tripping is for, in my opinion. Tripping is for seeing the world around you in new ways. Nature is the very best environment to trip in, if at all possible.
