hey there
I am actually training in florida, around the orlando region. I have never been into any Uk airspace or Irish, all i know is about the amercian one
Overall ATC is very helpful, depending on where you go and what time of the day. It was said before that you can fly into "busier" airports just like MCO , or PBI or even MIA, all of it is true. Even the parrallel approach into Palm beach next to the A320

Even though you land on the small 9R and he goes onto the 10,000 foot rwy 9L
It is great flying down here, weather is usually good compared to europe .. LoL , and no topographic features are of any danger execpt the big hotels !
Well I hope you will enjoy flying down here , if you need a safety pilot wou will be able to find plenty, most people are here to help not to rip you off

, just need to know the good place.
cheers
