Hi Claire,
And welcome to the Englewood site! I agree with everything that Amanx and Old Englewood have said, but if you want some advise from an expert shopper of clothes, handbags, shoes etc etc, then PLEASE PLEASE PLEASE don't waste your time going to Ellenton Outlets. This outlet used to be good, but over the past year or so we have seen it go down hill! The best outlet near Rotunda is Miromar at Exit 123 past Fort Myers - it is definitely one of the best! Also consider Gulf Town Shoppes at Exit 128 (before the one for Miromar). You could combine both in one day and have a mega shop.
As for Malls, I find Port Charlotte Mall as good as any, but if you want the likes of MAC makeup and Origins, then I would consider going to Edison Sq Mall at Fort Myers or Bell Tower Shops (again Fort Myers). Edison Sq Mall is a HUGE mall with all the usual department stores plus the designers names also. It can be found on US 41 about 35/40 mins drive from Rotunda.
You will be spoilt for choice .......... so do enjoy!
