Lol OP at your DD "why does Alyssa have completions no one else competes in"
She has the measure of Alyssa already!! Time for a debrief at home about how good your DCs were to go to bed like asked and that it was tiring that Alyssa didn't go to bed on the mummies. As you didn't get a relax, with adult time, which makes a rested and happier mummy. I'd be buying my DCs a treat once home for their good behaviour on holiday.
You be e been very patient and a good friend to be so chill and not say anything.
Next step: conquer my fear of a single parent holiday with just my kids and no adult company. I could guilt trip my sister into going with me but I really think this is a lesson learned about doing it alone.
Good plan OP as you found out it doesn't follow that going with another parent and their Dc will mean you get any quiet civilised adult time together if they parent differently. It'll be the first question you ask about bedtimes and what they'd do if their DC got up, if you ever choose to holiday with another family again.
I've had holidays like this and regretted wasting my holiday money and precious AL on a situ where the other parents who don't parent with boundaries.
I've had play date sleepovers with DCs who won't go to bed or at least chatter with the other DCs from bed, the whole point of sleepover- but insist on adult company and whine as mummy lets them watch TV downstairs with her (well I wish mummy had told me that .. then CF mummy does tell me that next day and how they don't get invited to many sleepovers ... ) (Do it once and no one more sleepovers for you at mine! )
This time next year though OP, you may have long term relationship of another adult (bf) to go away with. So there always that...
