to you all and thank you all so much for your input. It really can help to make things clearer in your own head.

mbear, they apparently roll the sides of the tent up in summer, but all the same it was terribly stuffy in there.

Celsie, great idea!! Thanks for that hun, I will look into that Monday and yes, I will let you know.

Janie and hoobs, true, true, true!! You would think that the older we get the better we would get and trusting our little niggles!

Lulu, it was very thick and stuffy air which may have been the reason he did that short breathing before crying. I can't ask him unfortunately!!

I've been thinking on and off about this today and I kept debating about calling or not calling them and didn't call, but I can do that tomorrow or we can go there and I'm almost certain that I won't even need to take him near the pool before he'll react and that will be enough for me to go shopping instead! Seriously though, I kinda have a feeling that I won't take him cos I just feel like that now. DH does have a say, but if I really feel this way he won't do it either. He may want to go and just see the place though and that's ok with me cos he won't force anything.
