We have been in Florida on Labor Day but can't remember the opening hours of the shops, sorry.
We took T-bags with us last time, and had no problems, the immigration officer found them in my parents case and all he said was "You English and your tea" and chuckled. I have heard of people having t-bags confiscated though, so it would seem to depend on the officer at the time. You can buy T-bags in the Ethnic section at Publix, prices are a bit inflated but if you are desperate for a good old English cuppa its worth it.[msnsmile2][msnsmile2][msnsmile2]
