I just arrived on Santa Cruz today and decided to ask around for prices. I actually booked a tour months ahead thinking that Christmas will be very busy. An 8-day mid-range tour which goes to Genovesa, Espanola, and Floreana, along with a few other islands, was about 3k. I only made a note of these islands because everyone says they're the most impressive.
Already, I was easily able to find tours that would've left tomorrow and the couple of days after. A similar mid-range tour going to the same islands over 8 days could be had for 1.5k, which is ridiculously cheap compared to what I had to pay.
There's a good chance that I'll come back again one day to visit western Isabela and Fernandina so I'll definitely try going for a last minute tour.
I'm just wondering if I jumped the gun by booking so early? Is it typical to be able to find so many tours still available at the economy, mid-range, AND luxury categories last minute at almost any departure date one desires?
