I'm planning my diving first trip to Galapagos.Instead of doing a liveaboard,I plan to do a week of land base diving this mid-August,from Puerto Ayora. I plan to dive with Scuba Iguana, but would like to stay at a hotel near Scuba Iguana and walking distance to the town center.Besides Hotel Galapagos,are there any other nice cheaper hotels within walking distance?Hotel Galapagos is about $70 a nite with breakfast and taxes included.Also should I book my dive trips with Scuba Iguana prior to my arrival, or I can just contact them when I arrive in Puerto Ayora?For those of you who have dived landbase with Scuba Iguana,and have stayed in the nearby cheaper hotels,kindly share your advice with me.Your recommendation is very much appreciated.Thanks in advance.
