Hi! We'll be on our 1st Disney Cruise (3nt) in Aug. A few questions for the veterans. Are all 3 nights on the cruise "resort casual"? I realize this means khakis and polos for men, but what about women. Are capri pants and a nice shirt dressy enough? Are tennis shoes ok? They'll be 4 in our party 2 adults and 2 children, if we request a small table, will we most likely be by ourselves? Last, is there any chance we might be upgraded or is that not very common on Disney? We'll be traveling in late Aug, so is there a chance? Thanks in advance for any and all help!
