Anyone had/been to a beach wedding?

Planning a wedding for November on a beach in St Augustine, FL for sunset (I live a few hours away). After wed set off some Chinese lanterns into the air over the water, then we’d be paying for everyone to eat at a cool restaurant we love with live music, with cake & photography. The company we’re going through would provide seating and nice decor & then wed be able to decorate the tables at the restaurant (lanterns, garlands, candles). The company has a bunch of great reviews and beautiful photos, however after communicating with them there would be no sound system so we’d have to hope they can hear us exchanging vows. Also worried about guests having to take their shoes off & if we’d have to pay to have some kind of station where they can clean their feet off? There will be about 25-30 guests, and everyone will be driving themselves to the dinner reception. This is all we can afford as we’re trying to buy a house as soon as possible. Does this sound nice?? I overthink and am afraid it’ll be tacky?
