@Inna22 As far as getting tips from someone they've never met, I don't find that particularly strange. They are asking because as a local, you obviously know more about the area than they do. Which doesn't mean we know what sorts of things they'd be interested in at all, (some people love museums, others are bored to death by them) of course, but we at least have an idea of what's available.
I am able to tell confirmed guests, for instance, if they ask about car rentals, that the town is easily walkable, that there are buses between the various towns around that run at least once an hour if not more often, that there can be issues with booking a car rental at the airport where those who have done so ahead of time get hit up with extra insurance fees beyond what they paid online when they booked it, and that there is a good car rental place in the town 20 minutes from here which doesn't try to scam anyone.
But if they ask for surf school recommendations (there must be at least 20 in this tiny town) I can't help them out with that and just suggest they google surf schools in Sayulita and email a few and decide from there.
If you get a lot of these trip planning requests, maybe that's the universe telling you you should start a side business and charge for it 🙂
