I highly recommend this tour! First day starts off with a long boat ride and straight to going to 3 spots to snorkle. I suggest having a light breakfast (boat ride may cause motion sickness) and bringing along a drink and snacks as snorkelling can be exhausting. The guide had a gopro which he took plenty of photos and sent them to us! The lunch provided afterwards was good (just 3 options - noodles, fried rice or curry) and for some people, it may not be enough - as Aussies, we're used to bigger portions and the snorkelling made us very hungry! After dropping us off at the accommodation they offered to leave one of the scooters if we wanted to tour Nusa Lembongan (we did drive a bit but it was quite difficult). The beachfront accommodation was excellent - breakfast was included, view was amazing and the staff were very helpful. The next day someone came by and picked us up for some driving and touring Nusa Penida - wear comfortable shoes and something nice (if you're into having great insta photos). Lunch was provided again - very simple Balinese dishes. Overall, definitely go with a tour if you want to visit these island and I recommend this one!
