If you RAF you can also chain summon. I tested out the Lyceum in BRD by running my boosting toon (non linked) and another 70 on the vet account down to the bottom. Then summoned the low level RAF toon, switched on the vet account to the noob and summoned him down. I have gone all over the place using creative chain summoning. I also have a lock on my vet account so I can even more creative.

I also use chain summoning to handle vendoring. Hearth home sell/mail/train etc. Get summoned back. Rinse repeate per toon.

RAF rocks for so many reasons. I will be sad when I loose the summon bonus.
