Hi there Becky
The pools pretty good actually, a good size, there is a couple of smallsteps and a rail into the shallow end which will be ideal for your children. The pool has got the usual deeper end at the opposite end. The only disadvantage i feel is there is nothing to seperate the shallow end and the deeper end, however, it does slowly get deeper, not a sudden drop.
The pool does get some shade in late afternoon which is quite good. There is a seperate toddlers pool which would be ideal for the two year old.
Finally, there is also a hot tub which is great, especially after a hard days theme park visiting.
I think the pool stays open untill 10pm, it opens very early, before breakfast.
You can buy drinks and snacks from the pool bar, and ice creams.
Very clean and well maintained, plenty of sunbeds and umbrellas, very nice pool area overall.
Hope that answers your questions.
Linda
