Me! I’m a single parent too and I would highly recommend doing stay and play as they get swimming and entertainment at night included & you can book activities although I find that some aren’t really for her age range and quite pricy for what it is
We’ve been to devon cliffs, primrose valley, golden sands, and presthaven all for a week and the first times we go to a new haven I didn’t bother doing stay and play as I wanted to explore the area and there was other things to do.
We are going to Hafan Y Mor in April for a week (not been before) and I’ve got stay and play as I want to be able to take her swimming and go to the entertainment then in July we are going back to Primrose Valley. I book my Haven weeks a year in advance as they’re always £300-500 for a week with the play passes but if you leave it they’re obviously more expensive. We love Haven, I think it’s such good value for a break and there’s always loads of stuff to do. I always try and get a 3 bed so we have a room for stuff but it’s never the end of the world if we just have a 2 bed.
I also do a food shop for the week and take it with us / or go to a local Tesco, Asda close by and stock up! My fave Haven is Primrose, we went up to Whitby and down to Bridlington, Scarborough too and it was just lovely - the sun was shining and we had so many beach days! If you know anyone who works for the nhs you can get 15% discount I think and they don’t check either , when I was non nhs I used my friends discount, but now I’m nhs it’s fine anyway
