I strongly recommend booking all activities in Lagos (or the Algarve) directly with the companies organizing them, and avoiding using "Ticket Shop Lagos" as an intermediary. Very simply, it is just simpler and safer, and had we done the same, we wouldn't have lost one day of our holidays because of their lack of organization and reliability. Unfortunately , we made the mistake of of booking our kayaks through the caves in Lagos at their shop in the city centre (a "convenient" option during an evening walk). On the day of the activity, we were very upset to find out from Kayak Tours (the company organizing the kayaks), that Ticket Shop Lagos had forgotten to register us for the activity. Worst of all, we were not the first unhappy non-registered clients of the summer. Indeed, we observed that the majority of the participants of the activity had booked directly with Kayak tours (at the "Batata Beach"). Luckily, we were still staying one more day in the city, and we were able to take the kayaks to Ponta da Piedade one day later.
