honeymoon vacation spots?

I’m looking for great place to honeymoon. something that won’t cost me a ton of money and somewhere we can relax and enjoy each others company but still have fun stuff to do. I want to get some sort of package. Does anyone know of any good ones? Where can I get one at? And of course how much does it cost?
we will be traveling next year at the end of july or the beginning of august. we only want to be away for about 5 days. we are having a new baby in january and I don’t think I will want to be away much longer than that. we like a lot of different things so it is hard to pick just one. I think maybe somewhere warm with nice weather.
oh we live in illinois by st. louis
it would be best if we could drive and then take a ship to the destination if that is possible. my honey hates flying.
