"but you may get only a /64 prefix"
What's wrong with a /64 prefix?
How many devices/subnets are you planning to set up that a /64 is insufficient for your needs?
"(which makes using VLANs an issue)"
How exactly? VLAN tags are entirely different to subnet masks. Also once you have a prefix you are free to split that prefix however you see fit, 2 subnets with /65 prefixes? or 4Billion subnets with /96 prefixes?
