Hey, great question !
One tip I use for all my holidays trip now is to make sure I have at least one day a week with no plan, no gatherings or big meals, nowhere to go and nobody expecting to see me. This is my day, my ME TIME, I do what I want and I self care, so I can enjoy the rest of my week 😉
This has really changed my holiday and my ability to enjoy fun activities, being with people, and feeling rested at the same time 😉
