This seed creates a world of islands with two ocean monument not far from spawn. Its spawns you in a dual survival island system. One island contains the trees you need while the other has multiple openings into a cave system with iron and coal. Just east of spawn is an ocean monument to explore. Past the monument a bit further are is another system of islands comprised of many small islands right by another ocean monument. Also, if you want to leave the islands, the mainland is located a short distance south of spawn.
For some reason, whenever I add locations, the submission page glitches out, so I'll post the coordinates here.
First ocean monument:
X: 294, Y: 61, Z: -216
Second ocean monument:
X: 583, Y: 61, Z: -422
Oh, and I'm pretty sure this seed works for 1.8 and 1.9 in addition to 1.10.
