I live on the North, in EA2/NV land but I'll try to give my point of view.
Here in the North of Spain, it is frequent to carry out activation on 2m succesfully for SOTA.
Nevertheless I know some EA2 activators have tried activating VHF only in other areas (EA4 EA5 EA7...) with less success. They frequently ended doing it on HF because of the lack of chasers.
A quick view in the Sota Database revealed some 26 chasers so far in EA7, and only 7 Shack sloth (frequent chasers...), meanwhile for EA2 we are 135, being 48 shack sloths; you see the difference? It's not good news!
So, how could it be improved?
You could announce the start of the activation via local repeaters there. Spain is plenty of open relays. The only trouble is to be able to announce that in Spanish, I guess not that easy for you?
Other idea if you know the activation date is to put a Spot in the DX Cluster and not only in SotaWatch. I know many spanish awards chasers read frequently standard Cluster. If they see your spot, probably will try to catch you.
Concerning english speakers for the qso, you'll get some trouble....
What if you learn some key words to complete the exchange?
Your signal report is 59... Tu senial es cinco nueve
Mi reference is... Mi referencia es SOTA EA7/...
May I suggest using google translator with built in Speaker so that you can try and learn the sound of such key words?
I could provide some more qso standard messages in spanish for you...
Anyway, if you are able to carry your little pole (I think it does worth it) you'll get more chances to succesfully complete your activation with less stress.
Stay tuned if you need more info.
