I went on two spring break trips while in college, so I’ll just detail those and if its for you go for it.
My Junior year me and 12 friends (including my g/f at the time) rented a house on Mexico City beach (Florida pan handle). It’s about an hour or so east of Panama City (which is a huge Spring Break destination). We were on a peninsula in the gulf of Mexico, and there were tons of vacation houses there (probably 20 in our “block/suburb” alone), but hardly anyone was there. This was great for us since we brought 12 of us to begin with, not to mention tons of alcohol. About a half a mile down the beach there was a similar sized group from another large school (we were Ohio State, they were Oklahoma State, oddly enough the two OSU’s), and a bit further from them another group from Maryland. My g/f and I thoroughly enjoyed the whole trip and had a ton of fun. The single people in our group got a bit restless, but I mean we had a beach largely to ourselves, had a couple beach bon fires…. and we even drove to Panama City for one night to experience the full on Spring Break madness.
My Senior year it was me (single this time) and 10 friends. We went to Tybee Island Georgia. This was a lot less secluded, but more family oriented (in fact our “landlord” lady made it very explicit this wasn’t a typical spring break hang out and if we got out of hand she would kick us out). That said, there were many more groups of students than the year before, not to mention people in general. We didn’t have the seclusion but it was still fun, though Atlantic water is cold. Also on the plus Tybee is like 15 minutes from Savannah, which is by far and away the most beautiful city I’ve ever been to in my life. We spent a whole day there walking around and checking out shops and eating and stuff. We also built a potato cannon from parts at the ACE hardware on Tybee, and fired it into the ocean.
