Thanks everyone for the help and advice, I have passed it on to them, and they were saying it's probably going to be a walk in the park and maybe a small picnic if the weather is nice.
That is really great!
With my ex it was always a bit tricky as I had a good income, he didn't have anything much and didn't want me to pay all the time. But we still wanted to go places and date etc.
Often we did something like a walk which could be the beach or the woods etc. And sometimes we got nibblies and drinks in the supermarket and had a picnic somewhere, enjoying good conversation, each other, and many times a glorious sunset :)
He had woollen ponchos in the back of the car, so if it got cold, we'd wear those.
Other times we went to the beach to enjoy, sometimes swim, then have a BBQ at the beach :)
Or we went canoeing before the BBQ (he had good inflatable canoes that easily fit in the trunk ).
Such things don't cost much and to be honest, to date those were the best dates I've ever had!
