$45 per night?? Marginal, unless big drinkers. If 2 adults and a child then definately. If 1 adult, then probably not. If you will be out and about and miss any AM or PM use of club they probably not. If you are going to "hang" at the property and use the club at every chance then go for it.
We, as Diamond's, got it free. We thought the club was well worth that and more (heh, heh) but $22.50US each per day, I doubt it.
