A few thoughts:
- €132 per hour for a C150 Wet is not exceptional value. You could do that in Europe. You can do it wet in the US for less than $100 (€92) per hour if you really look
- Of course the US has the advantage in areas like landing fees. It's one of the big advantages, along with the vast array of airfields in places like Florida, of flying there.
- Being instructed and counting it as PIC time is a touch dodgy, don't you think? There's a reason it 'wouldn't happen in Europe'. Did the instructor count it as PIC time as well? You don't need to answer for me to know it's yes. Under FAA rules, that might be fine once you've passed your FAA check flight (a cost and extra step you didn't mention BTW) and legal to fly as PIC, but it certainly isn't fine under EASA rules. Plenty have got away with it, I won't deny that. Probably best not to boast about it online though.
- You certainly don't need 15 hours to 'get used to the airspace'. A couple of hours should do and maybe a couple more if you're new to the Cessna. Did you pay for this 'instruction'? 15 hours is going to add up very quickly if you do.
- Did you get an FAA PPL or did you simply verify your EASA PPL? Two very different things. The latter is pretty easy to do.
- The accommodation price does actually sound very good value. Under $100 per night is challenging in Florida nowadays which that makes HB there less competitive than before.
- You can fly 500ft above beaches in Europe too. No need to go to the States to do it.
