I know I will get slated but just want a moan. Ils have a seaside cottage which they rent out. They go 6-8 times a year themselves, they invite sil and her family to go with them probably 4-5 times a year. They never invite us. We get a week for ourselves and sil gets a week. As sil children are under 5 she goes September. I work in a school so hols only, first couple of years we went in summer hols. But then ils said out of season only. So we either go oct or feb half term for a week. Found out today ils, sil and her family went up yesterday for a week , it's possible it was free but I find it hard to believe it was empty aug bank hol. So seems more likely ils booked it and invite sil. Feel really annoyed unfairly treated.
