How about a low altitude spawn just off a beach shore, with a "rope and anchor" anchoring it to the beach (mainly so memebers can climp up to the spawn). Furthermore, by having it slightly off shore, members can also jump off anywhere and land saftely in water.
I chose an underground crashed bus at the beach.
You know that would be awesome.
Crashed bus would be awsome if done right but it would need to be massive to get it to look detailed.
