I have taken a look at those packages, but apart from the advantage of not having to take care of logistics myself, I see a couple of disadvantages: they still seem a little bit more expensive than organising it myself; and I need to have Troy all by myself without the slightest time constraint :-) Now I am also considering if I can extend to Assos on the same day, and then go back to the City in one long transfer on the next day, overnighting again in Çanakkale. I like the idea of being a little lazy on the coast in this lazy season. Maybe I'll also manage to visit the town properly with no hassle.
OK, I won't be so desperate of missing the bridges, but I hope to come back for them, too! :-)
