Wedding help!

My wonderful fiancé proposed to me 3 months ago after two years of being together (and after 4 years of loving each other! 😍). He's 43 and honestly thought marriage wasn't for him until he met me (awwww). I'm divorced so I've done the wedding thing, although I was super young and poor so, itll be much different this time around. Neither of us want a big wedding--just family and maybe a friend or two--no more than 50 people including kids. We have NO IDEA where to have it or anything. He truly doesn't care about the details or the money and neither do I. But I'm stumped. My last wedding was super informal, outdoors at a park with potluck style food. I don't want that again... any ideas?? Destination wedding? Beach? My mom's backyard? lol. Oh and we want a taco bar... that's our only requirement 😂 I'm 10 weeks pregnant and we're in no hurry so it'll be after the baby is born... probably early fall 2019.
