Not at all, Leclairage, not at all. Don't know too much about the various airports in northern Spain and Balearics, but as you say you'll come in May, make sure you check the NOTAMs as the larger tourist destinations (LEMG, LEIB) tend to prohibit / severly restrict VFR traffic during the 'season'. LEMG for example is out Thur-Sun now

and
AFAIK LEIB and LEPA do apply similar rules. If you're IFR you're ok, though.
Generally it's very pleasant flying here, as you seem to know anyway. Have a great trip
