using IPv6 address block across multiple locations

My take on the issue is that your providers are wise in not wanting to
accept prefixes longer than /48s.

You should get multiple prefixes, from the same or different RIRs. If
there are policies in place which do not allow you to do so, I think
it's a good time to discuss them.
