What locations do you want to see?

[Angellos]

Garlemald, obviously.

[Kobalos]

Garlemald and more of Hingishi - At the moment we only have the city Kagune

[OrangeCrystarium]

I want to go to the New World and see the Whalaqee tribe's homeland, maybe even learn more about the origins of the Mamool Ja. Also Meracydia, even though most of that place is probably a pile of rubble by now. Radz-at-Han in Thavnair has been mentioned quite a lot during the game as well, would love to see some Arabian-styled towns and cities.

[Halivel]

I would like to visit Sharlayan and the Old World. I know that Ydillshire is part of it, but it would be really cool to discover the whole region, and find places where almost all Scions came from. It would be interesting to visit Meracydia as well, because according it's description, there are still some people living, and there were suggestions that Miqo'te originally hailed from there.

As for new possible locations... Moon? Ahah. Other reflections of our realm, too.

[Riardon]

A massive underground enchanted cave area with an underground city (Give us the Duskweights areas).
More European forests with castles (and a nice opportunity to introduce vampire hunters and vampires).
Tropical islands.
The New World continent in America's style (Whips and cowboys should be a class perhaps Beastmaster/Tamer)
Meracydia
A frozen continent like Antarctica.
More Shards obviously.
Expand and revisit the old 2.0 areas (Western Gridania anyone?)
Garlemald and Ilsabard.
More High Fantasy areas.

[Shurrikhan]

The Waste, via partly auto-generated open world exploration with seeded common elements anyone could simultaneously stumble upon.

The Deep Shroud. Make me fear the elementals again. Or worse.

Areas near but not directly within the former Sharlayan sphere of influence, preferably with interesting beast-tribes and something faintly... off... about the area's magic.

A Black Rose testing site that leaves in its wake a Call of Cthulhu-esque Steampunk&Occult Victorian fantasy setting.

A jungle area (perhaps also with scattered urban pre-ancient ruins, maybe Allagan but preferably not) with mixed instancing, in which we can become faintly tainted/gifted by Zodiarc (or some aspect thereof), to the extent of needing to both exploit and restrain newfound abilities. Sort of a meta-zone, where a dense and sprawling semi-instanced world that can take a good half-hour to traverse due to verticality and lack of mounts gives position to numerous open-world dungeons. Perhaps we initially drop in alone in random areas unless in a party, drawn in during our dreams or whatever. From there you survive, work your way to the surface or to various uninstanced (or, less instanced) camps, etc. Think of it largely as a replacement for PotD, just with a whole lot more aethetic impact, personal progression, and a plethora of hand-crafted settings.

[Senn]

Just had another idea. What about an entire zone where we're inside a giant creature's belly?

[TheGrimace]

Lea Monde of Vagrant Story is officially a citystate in FFXIV. Unlike Vagrant Story, it is still bustling with activity.

I want to go there. Bad.

Also Old Sharlayan.

[Vestara_Khai]

A bunch of Cavernous Maws that looks like Atomos to spawn in all the areas and when you enter them it takes you to that zone as it was years ago. . .wait a minute. . .
