Village and Stronghold seed: legend of luuc
This seed allows you to find a Stronghold in a few minutes - which can really become a problem in some worlds. The right seed is probably simplest way to find Ender Portal, you will still need Ender Pearls though.
Just look at the horizon and you'll be able to see outlines of the village, go there and find a well, then dive into the water and dig until you find yourself on the hard ground.
