So, we are spending the first week of our honeymoon at a resort in Florida. Second week we plan on spending a few days between Disney and Universal (Hogwarts

) I haven't been to Disney in like 10 years, does anyone have any specific things they'd recommend doing, or any cost saving tips? We are staying in a non-Disney hotel, but it offers perks like free shuttle to and from the parks.
Also, any recommendations with St. Pete's would be great too
