OK guys - more advice please 
Just bought some holiday clothes.....not too much as I plan on buying most of it out there as it's cheap!
Never been to USA before....do most of you tend to do this??
Planning to get swimwear, shorts, dressy dress (for the cruise) and of course the timberlands! (will look groovy with the dress
)
Also, being the complete novice that I am....bought some suitcases,,,real cheap and one is HUGE! My sister (who travels loads) had said that the suitcases cannot be too big/heavy as the baggage staff refuse to handle them....is this right??!!!
