Relaxing “mini-moon” in Jan ~1k/night

My fiancé and I are looking to go away for 3-5 days right after our wedding in January. Typically we like to do a more active vacation (museums/sightseeing/etc) but we are both so stressed from wedding planning, we would like to go somewhere where we can lounge around and be drunk/get massages etc. We are in the US and would prefer to stay relatively close by since we can’t afford to be gone for that long. We’re open to an AI but wouldn’t mind spending a bit more to be somewhere with good food (food is really important to us). Our biggest fears with an AI are being pitched to the entire time (we are very shy and private) or going somewhere with a party vibe(we are exhausted and want to go somewhere quiet). We wouldn’t mind somewhere without a beach, or even somewhere cold, as long as it’s somewhere pretty where we can relax and go to a spa. Our budget is about $1k/night.

Any thoughts? This isn’t our typical vacation so we’re having trouble even knowing where to start.
