when my son was young we tried each year to go to a holiday park, he ran out of school one day and it was mum mum whats the place we are going to, i told him and his friends mother said they would like to go, her son was lovely but the mum & dad were heavy drinkers and very loud, they booked it and we did not look forward to it, just a few days before we went my mil had a bad fall, holiday cancelled, we explained to the travel agent and they got us a holiday for later on in the summer at a different park, 2 weeks for the price of 1 and half board, it was the best holiday we ever had and my son still talks about it. i can understand how your husband feels, this holiday was exciting for you both and it does sound a bit like they are stealing your thunder by going first, maybe best to avoid them and if you can't just very nicely say, thanks but we don't want to know anything before we go.
