If you want to spend most of your honeymoon packing/unpacking, waiting at airports, spending hours on trains or planes, then stick with your plan. Me, I'd be steaming mad to be schlepping all around on my honeymoon. Remember check in and check out times...if you're thinking you'll be filling in the afternoons with some sightseeing just remember you'll be doing it all while carrying your luggage.
I get it's a big trip and you want to see and do as much as possible while you're there. Just think it through, and allot time for just enjoying where you are.
