Wow. There is actually one new to Mexico traveler. I am only too glad to help. Depending on when you are crossing there may be delays. Currently many Mexicans that live in the USA are returning to their home country for Xmas and New years. Should taper off by the end of this week. You do not need a car permit but will need to get an FMM. If you are staying less than 7 days it is free. Otherwise around $10.00. Make sure you tell the agent how long you are staying. I can recommend 2 parks. Depends on what you are seeking. For a true Mexico experience Islandia is OK. It is located in Old Kino is very rustico( this can translate to very crude or basic!). It is on the beach but spaces are not wanterfront. Full hookups but likely 15 amp. Lots of old timers with old units.Short walk to the old Town. New Kino is mostly Mexicans but also Americans and few Canadians. Kino Bay RV park is a modern facility. Mostly 30 amp and full hookups. They have some sort of WiFi. Well kept park with nice bathrooms, newer clubhouse. many regulars but friendly people. You are not on the water. It is across the street. For a newbie that would be my choice. Turn on private messages in this forum and I will send you my phone number and email. Would be glad to meet you in person and answer any quaestions. BTW: If you are a water person it is too cold for swimming.
