Hello and thanks for your thoughts! Family of 5, landing from Boston, USA in Ponta Delgada at 07:10 in early July- taking an immediate plane out to Horta that morning (leaving at 10:30)- staying for 5 days (time enough to hike, see the mountain on Pico, whale watch)- then fly back to Ponta Delgada for 5 days to enjoy all that island has to offer. What do you think? 3 islands in total. I plan to rent a car on Ponta Delgada but not necessarily on Faial (unless you think it's necessary). We are pretty adventurous and plan for a combination of go-go and relaxation. Thanks again. I can't wait!
