I thought the breakfast was plenty but it's not eggs and bacon mind you, just cereals, crossaints , bagels, yoguart , etc...
from what I remember , the beer and wine is only out from like 5p - 7p.
Yes, they have bottled water in plastic bottles.
They have beverages like soda, coffee and tea all the time . And usually there was a small fruit bowl out all the time (with oranges, plumbs, strawberries, apples) but mostly the food sticks to the schedule.
You can also get cabana rentals at the pool 1/2 off and free access to the fitness center.
For me, I think it is worth an extra 50 or 60$ in most cases. When I'd rather have the full breakfast in the restaurant - I go with a regular room. Otherwise, the continental breakfast is fine, and all the extra stuff is nice. I especially like having a place to take the children while my husband naps in the room or whatever.
