I also got the letter this weekend. We're not going until mid-May and DVC member services told me the work is scheduled to go on through July, but it's primarily the club lounge and soft goods, so I'm not overly concerned.
HOWEVER, I am posting with a new and different question. I am a DVC member and booked a 2 bdrm standard view at Jambo with points (for 4 of us), then a separate savannah-view studio for my son & his girlfriend via Disney reservations (using a TA). Due to today's 25% deal, my TA called to say she could save me over $600 if I wanted to change the studio villa to a regular savannah-view room. I jumped at it, and no matter what, I feel it's worth the money, but was trying to get a lay of the land to see how far away these rooms will likely be. We do have a "travel with" number attached to both reservations, but I'm assuming our odds of being on the same floor, or even marginally close to each other, are likely a lot worse now. I have looked at many Jambo House maps, but can't get a good idea of where the regular rooms are vs. the DVC studios. Sounds like the villas are mostly on the 5th floor? Is that true? So it's likely that my son will be on a lower floor? Different floors doesn't bother me as much as opposite ends of the resort would. Hoping our "travel with" will help that situation, but if anyone has any insight or hints regarding what I might be able to request to increase our chances of being as close as possible, it'd be appreciated!
Thanks.
