So after ummming and ahhhing over where to go for a holiday...we have finally decided (agreed ) on Cairns. We are going in the last week in May for 7 nights and staying at the Novotel. This is my distraction holiday as we are leaving on (what was)the EDD of my Jellybean so I want lots of ideas of fun things to do with DH and DS (who will be 22.5 months)

I have looked at the Barrier Reef and Island cruises which look fun (if expensive) and I'm sure ds would love the glass bottom boat etc and maybe swimming.

I also like the idea of the railway/skyway day trip as Ds LOVES trains (toot toots )

We are staying in Cairns itself to avoid having to hire a car. Hopefully it's warm enough to spend some time by the hotel pool but we'll still need some other ideas... So if you've been or you're a local, any tips, ideas etc? A good day spa would be nice, good restaurants (family friendly) plus I'm coeliac so if you know any places with a clue about gluten?

Thanks in advance
