Not a guaranteed benefits but... access may be available
While microwave is not one of the advertised benefit of worldclubs, I must say that most worldclubs do indeed have a microwave. Granted, with the "no food policy", you won't be allowed to use it freely to heat up most food but I saw a lady use it today, to warm up a baby formula. Lady came up to worldclub to inquire about the availability of a microwave today and the worldclub agent assisted them with the access.
So as for most of us who want to reheat their food, it's likely a no-go, but for other needs, it's allowed, provided they have one.....
