Hi,
Not sure I am going to be of assistance here with specifics [or pics], but I'd be glad to give some info and advice. So just about everywhere in WDW is awesome for Photos, IMO. Might I suggest pics of Pluto w your pup!! That would be soo kewl!! You also have your basics, pics in front of the Castle, EPCOT ball [Spaceship Earth], etc. For resorts I find that The Poly, Beach and Yacht Club(s) and Port Orleans, IMO offer the most scenic views.
Might i also suggest a theme photo op like a 'pup around the world' ?? I.E. take your dog around the countries of EPCOT and get pics with either a cast member and/or with something iconic, from each Country [like the living statue in France, the photobooth in London or the Troll in Norway]? I always like to 'theme' up a visit, especially if I am in a rut with my photography [such as pics of attraction signs or only Mickey colors or something like that?]. Hmmm, this might make an interesting post??? LOL
Anyway, I am certain there are far better photographers here that can provide some awesome specific examples and I hope this gets the thought process flowing [for you and them!]. Please post your pics once you return as I would love to see them! All my best and...
Kungaloosh!
