We were there the first week of May and it is lovely :-)
I haven't read your whole thread, but some of the points I picked up skim reading ....
We seemed to be permenantly eating and drinking - the mealtimes come round fast! So we didn't buy any additional drinks over the full board plus package. We took a bottle of duty free for ore dinner drinks while changing for dinner, though shop over road is just as cheap. We got water and come etc there too.
Own drinks by pool - there are signs saying don't, but we did, just discretely. We didn't leave bottles out on sun eds etc, just got 500ml bottle out of bag, had a drink and put it back in bag (where it kept cooler anyway). Drinks at pool bar etc were expensive, though ice creams were ?1.50 - ?3 (but there is ice cream at every lunch and dinner for dessert too).
Taking wine etc back to the room is not allowed because only drinks with meals are allowed. It's amazing what you can fit in a buggy basket tho 
The playhouse is fab and they have stay and play sessions too, if you kids are under 3 or don't want to go to the supervised sessions.
You don't need to take any towels - you can borrow as many as you want and change them for clean ones whenever. You can take them to the beach too.
The beach outside the hotel isn't brilliant. Turn right and walk along to outside the lyttos beach hotel (it's white and has manicured lawns - you can't miss it!). It only takes 5 mins to walk and the beach is better.
Have to dash, but have a fab time :)
