I don't think the "Vacation EDC" is valid. It's not EDC if you don't actually carry it with you, or at least have it where you can easily reach it, more days than not.
Alternately, if you really are on vacation 51% of the year, I hate you.
Sounds like you don't get too much vacation time

Let's see in more details what Vacation EDC would consist of:
This one would have to include airport DC (for Daily Carry, since we don't spend multiple days in a row in airports) = bags, passport, tickets.
Once at your destination you might wear/carry things you don't when at home like sandals and flower shirt or bathing suit. Those would constitute your Core Vacation EDC. Then you might want to leave your home keys in a safe place, but still need your wallet and hotel key (Basic Vacation EDC, which might include passport in foreign countries). Then, as a flashaholic, you'll definitely have some Regular Vacation EDC (probably a smaller flashlight than usual, water, touristic maps, etc.) Then there's the Daily Vacation EDC (towel, sunscreen-could be Regular Vacation EDC depending on your skin sensitivity). Vacation Car EDC usually constitutes only in car rental agreement and maps. Extended Vacation EDC is the toothbrush and toothpaste you leave lying in the hotel room (ok, we need another term than EDC for this one). If you carry some sort of Work-Vacation EDC, you definitely need to re-evaluate to see if you're really on vacation. And finally Vacation-Vacation EDC = booze, condoms, cigar, etc. whatever makes the day go by and you won't leave behind.
So, any sub-category of EDC can be EDC -even combined with other categories.
However, you're right: while it's not
on you, it's not EDC, it's just stuff. Vacation stuff, weekend stuff, daily stuff, etc. that lies in drawers, closets and bins.
So, after pondering for a while, I decided we needed to extend into a few more categories. Now we have:
EDC (Every Day Carry) = stuff you normally carry in a particular situation (work, weekend, vacation)
DC (Day Carry) = Stuff you carry for a day on specific occasions (travel luggage)
C (carry) = Stuff you're just carrying and don't care about (ex.: empty water bottle while looking for a recycling bin, used condom, etc.)
Stuff = Stuff you're not carrying at the moment
EDS (Everyday Stuff) = Stuff that's been placed in a stategic location for momentary daily usage (the flashlight on your night stand or next to the door)
ODS (Occasional Daily Stuff) = Stuff like your luggage that's waiting in the hotel room for the trip back, at which point it will become DC again.
SS (Stored Stuff) = Stuff you're not using at the moment and that is not accessible.
As an example, luggage is normally SS, but becomes Stuff for a day while you're filling it. The next day it's DC on the trip to the airport, at which point it becomes EDC (since you'll always have that WITH you in an airport). It gets demoted back to ODS once in your hotel room, possibly even SS if you like to put your clothes in hotel room drawers. Then the whole process is then repeated until you get home to demote it back to SS level again.
