Yes, the experimental section is given to people with accommodations now unless you have specific accommodations that removes that section (which is very rare).
@"J.Thomas" yes, you can purchase now and use later—just write "Résumé Special" in the subject line when you get in touch. And yes, you can upgrade to consulting for $2585.
I'd just point out that just b/c a location had roomy accommodations in the past does not guarantee that this will be the case in the future. They can switch around testing locations within one campus from administration to administration.
