This will give you six villages and a sand temple in your starter (central) map. There are diamonds, obsidian, and bookshelves in the villages. Your spawn point will be in sight of one of the villages.
First: Create this Seed in a SMALL MAP: -3157814418872595889
Second: Find ALL SIX villages. Otherwise they won't appear right. (-249/312, -170/87, 111/334, -470/62, 355/-284, 305/-420, sand temple 243/-437)
Third: Re-size the map to Large; if you wish.
I have yet to explore more than a fifth of the total map after expansion. However, you WILL get at least one more village, another desert temple, a jungle temple, ravines, a mineshaft, a surface spawner, lots of big mushroom islands, several solid sections of extreme hills, steep jungles, a big taiga forest, more deserts, plains, rivers, lava pits, and spread out swamplands.
Basically this thing has it all, with a good central "safe" point to branch out from!
Thanks for sharing this seed! I haven't resized it from small yet, and I'm finding the reduced space rather enjoyable for starting out - it's a good way to make sure I don't miss anything, and if I have to leave some loot behind in a chest because my inventory is full it doesn't take long to run back for it after I unload at my base. It's great having so many villages nearby for trading, too. The only downside so far is not being able to ride any of the countless horses & donkeys running around because I haven't yet found a single saddle. I'm sure that'll change when I upsize, though.
I ran across a couple of surface spawners while wandering around & thought someone here might be interested: there's a skeleton spawner at -347/144, entrance on a grassy hill behind the tiny 2-house village at the northeast corner of the map, and a spider spawner at -369/-40, buried (but visible) under the sand near where the desert runs into a snowy area.

I must say thank you for this seed! I went on a trading spree last nite, and came up with major loot. I haven't explored since I resized the map, but I am looking forward to that. I am torn tho, my current survival world has been so good, mob grinder in the sky, full self-created village with huge amount of love crazy villagers, 3 naturally spawned Iron Golems, so much traveling, but I might leave that world for this one. I couldn't recommend this seed enough...
There's a cave spider spawner at 243/38/-457, with a chest that contained a saddle (for me, anyway - not sure if chest contents are randomized). It's sort of on the way down to the ravine proper. Dig on the side of the temple farthest from the village, in front of where the main temple entrance is buried, and you'll find a way down that leads to the spawner room.
