We have some family business to take care of specifically in mid-March and specifically in Miami and have decided to extend a few days to make a mini-getaway out of it. (We also could stay in FLL and travel down to Miami on the specific day we need to be there.)

I would love tips on how to make this as fun and relaxed as possible and not feel like we are surrounded by drunk spring breakers the entire time. My thought is to stay at a nicer resort ($300-400/night seems like the rate for those dates). Some older HB posts suggested Loews, etc. which are like 2x the price and thus out of our range. I am looking at Costco travel packages because we have had success with those in the past.

Any and all suggestions are welcome. We would be interested in non-beach day trips such as Zoo Miami or kid-friendly art museums and the like. LO is 2+ so simple stuff like pool, sand and beach is also just fine.
