I just returned from Spring Break with my group of moms/girls. The airlines did not ask about a letter from the father to exit the country. Passports are the only requirement. So save yourself some time and energy and skip the notary.
Body Guards/ Security/ Chaperones/ .....100% effective and necessary to babysit teenage girls. I have to admit that I was skeptical about hiring someone (after all the laughs on my thread) but these guards did their job and were worth every penny. Our concierge made all the arrangements although I am aware that other groups from our HS used an agency. Our hotel was very quiet in the evening so our teens went out clubbing each night. The Zoo, Roo, Mandalas and so forth. We had many rules regarding safety which we repeated to the girls on a nightly basis. We always had at least 3 moms along (one in each cab) with a 2:00 am curfew. Once the girls were back on the grounds of our resort, they had until 2:30 am to be in bed! They were not allowed on the beach at night. The security guys were super professional and went into the clubs and watched. The moms sat either outside or at a table away from the dance floor. It was a brutal 3 hours each night watching kids doing shots of tequila with thumping loud dance music.
I witnessed a street fight between 2 in which police were called and a window was smashed. I saw the paddy wagon haul them away. I watched kids leaving the club and heading to the ocean with security guards on their heels forcing them back inside. I placed a HS student in a cab back to the hotel and later learned he arrived passed out. A body guard at the hotel (hired by our HS group) carried him out of the cab. As the night progressed, more kids became ill. This is spring break 2014 with teenagers. It was not a family vacation. I knew what I was signing up for. When someone asks me how my trip to PV was all I will say is that " the weather was perfect."
Tip... skip the Foam Party.
