i know you already made your decision, but for myself and my family (my parents and my three brothers) we always stay on club level. You are getting a great deal -we are paying 319 a night for june 20 check in (APH) - but even if your rate was not as awesome as it is, i would tell you to go for it.
It is on average about 75 - 100 more a night, but for the complimentary soft drinks and water all day long - it is well worth it. I think a bottle of water in the park is around 4 dollars. Sure, it is probably cheaper to bring your own drinks from sam's or publix, but the convenience of it is unsurpassed. Plus, you do not have to worry about running out to get more, or lugging any extra home.
We typically wake up and have a small breakfast in the club room which saves even more money. It also depends on how many people are in your party, how many children you have and whether or not you are big breakfast eaters. It is basically continental with a little more. They have all the bagels and muffins, coffee, etc, and typically a hot item that changes daily. Cinnamon buns, maybe some eggs, that sort of thing.
We do not take advantage of the lunch because we typically eat out in the parks- and i think that we always miss the deserts, but everyone in my fam (with the exception of one) is now 21 so we take advantage of the free wine and beer happy hour.
We have had the dinner a few times. Food is good. I think that it is kind of hit or miss depending on your likes and dislikes.
Plus, I beieve that the Portofino club rooms are bigger than the Portofino standard rooms. Someone may be able to verify, but i think that is what the reservationist told me.
I know this was quite lengthy, but i wanted to point out what my family feels the value is. Our party is quite large - especially when you add the two nephews, a niece and two sister in laws - so the drinks throughout the day make it cost effective for us as well as that little bit of extra space in the room.
I can let you know more after we stay. This is our first portofino stay - but we have done club at both RPR and HRH so we can well attest to the value of club level. Enjoy! and let me know how it goes.
