HRC All Access Membership - Food credit expiration dates?

[TreeOfLife]

I recently joined the RFC club hoping to use my $10 credit during our trip in December.
It turns out the voucher expires in may...

How about the All Access' $20 value toward food, beverages or merchandise purchased at the Cafes voucher... When does it expire? In a few months? A year from joiining? No expiration? Are we better off getting this membership closer to mid-year? Thanks...
