kid bday party fri, sleepover drop off sat morning, couples weekend sat night — i am DESTROYED

pls send help im writing this from my sofa on sunday at 4pm w a face mask on and a litre of water and i still feel like i got hit by a bus. F36 dh 38, two kids 7 and 9, weve been LS abt a year. we have started doing one proper "couples weekend" a month (hotel sat night, sometimes a club, sometimes a private meet, depends). and i love it. i need it. its weirdly become a thing that keeps me sane in the chaos of having two primary school kids w big social lives. PROBLEM is the math of being a parent w kids who have social lives + LS adults who also have a social life. yesterday looked like — friday 5-8pm kid one had a bday party (i was the parent doing dropoff and supervising the older kids bc it was a sleepover-adjacent thing, didnt get home til 9.30pm). saturday morning 9am drop kid two at HER sleepover w a friend, then 10.30am drive kid one back from the bday house. then i had abt 4 hrs to do all the normal saturday house stuff plus shower plus get ready plus drive to hotel. dh similarly slammed bc he had his own dad jobs. by the time we walked into the hotel at 5pm we were already DONE. and we still had the actual fun thing to do. we did go out, we did have fun, we got back to the hotel at like 1am, slept maybe 5 hrs, picked the kids up sunday at 11am (both from different houses, hello more driving), and have been on the sofa since. how do other parents w an active LS life ALSO survive the saturated weekend ecosystem of primary aged kids?? do you ever just say no to the couples weekend bc the rest of the weekend is already destroyed?? do you outsource pickups?? do you swap weekends w other LS-friendly parents?? do you just power through and write off sunday?? i love all of this stuff and i wouldnt trade any of it but i need a better engine.
