I can't find Part 3 (Maldives) and Part 4 (Dubai) yet, but judging by Part 1 (Turkey) and Part 2 (Egypt--to which I replied this morning) please accept this piece of advice from an experienced international traveler: It appears that you are trying to do FAR too much FAR too quickly. So far it looks like you haven't included anything for the R&R phase of a honeymoon--romance and relaxation. Perhaps you intend that for Dubai--if so do be aware that Dubai is an extremely expensive place and even in October it will still be very hot and hideously humid. Those things like an indoor ski slope and man-made "designer" islands don't come for cheap you know. You'll also have very little if any contact with the real people of Dubai as they import their workers from places like Sri Lanka and India where the people can handle the unimaginable summer heat while working for peanuts and living in very poor conditions as they serve the whims of oil-rich Arabs. Of course the architecture is literally fantastic :) Perhaps the Maldives are the R&R portion. I have no knowledge of that location.
Now an important question: Presuming you are flying from the USA (which time zone?), what is your first destination? If Turkey or Egypt where have you allowed time to adjust to the time change of anywhere from 7-11 hours? Please accept the advice from a frequent traveler from the USA to that area when I say that adrenaline and excitement can only last so long before the jet-lag hits--HARD. The more you try to fight it the longer it takes to recover. If you're sensible and plan for at least a half day for recovery (and the two of you might need it at different times) you'll most likely be highly appreciative of this advice.
BTW, if you haven't made airline reservations yet, I cannot give higher recommendation than to use Turkish Airlines as much as possible and most certainly for USA - Turkey. They have non-stop flights from six or more US cities from NYC to LA. Excellent food (always included) and free beverages of all kinds on international flights.
Now back to Turkey: Personally and from a great deal of experience I suggest that you somehow add two or more days to your time in Istanbul--most certainly if such is your first destination after a long-haul flight. The time- and money-saving Istanbul Pass is valid for 72 hours (three days). It gets you into most of the major sites in the Sultanahmet area (the amazing Basilica Cistern is a very noteworthy exception) and it takes nearly every bit of that time to visit what is included unless you fly through so quickly that your eyes scarcely have time to focus... I've spent well more than a month in total in Istanbul across many visits and will be there tomorrow for another week. Guess what? There is STILL much of interest for us to see and do for the FIRST time and other places to visit for the second or greater time! I say this as a "country" person--I've lived in SE Missouri most of my life--who doesn't care much for most large cities both within and without the USA.
Your three days for Cappadocia is reasonable but not generous--in fact it is about the only place in your itinerary that I've seen so far that (to me) has a reasonable amount of time devoted.
