Very different experience here...I'm an email person and do almost all my communication thru email...my guide (who uses his middle initial in his email address, so it's
Name.I.Name@disney.com) is perfectly fine about emailing w/me...did an add-on last Jan which I initiated thru email and would have completed thru email, too, except I didn't want to send my credit card # via email so instead we arranged a time to transfer the card number by phone...
Only once has he not responded to an email...I suspect that email got lost since it's so out-of-character for him to not respond.
Maybe the difference is that I told him upfront that to communicate w/me would require use of email...if I had to do what I have to do solely by phone, I may not have purchased
DVC...for me, pure phone contact is a big hassle (consequently, I use the website to email in my reservation requests 90% of the time...of course, 90% of the time we're traveling at low-DVC-use times, and I'm planning at 11 or 7 months out, so it's not a problem...for T-giving, I do call)...
