I'm not local either. The 90 day window meant two of my three usual trips at the end of the year were cancelled to prioritize my favorite of the three because all three of those are usually at least 5 days.
My trips average 3-5 days each throughout the year. Sometimes even more. So I would hate if I had any less than 6 reservations. At least with 6 I might be able to reserve two of my shorter trips that are within 90 days of each other without much issue.
30 says would be fine with me. I would not want fewer reservations, though.
I'm worried about what the 90 day reservation window will mean at renewal time
I had been saying this exact thing since before the keys launched. The 90 day reservation window with 4 or 6 reservations is too long of a period with too few reservations. Once enough people got passes, this nightmare situation where everybody needs to get reservations 90 days in advance will play out and then people will discover they don't have enough reservations to cover their visits. Between the longer reservation window and removal of "good to go" days, the Dream Key seems worse than the Flex Pass. The only surprise to me is how blatantly Disney is punishing keyholders with the reservation calendar compared to tickets. I thought they would at least try a little harder to not upset people who spend the most at the parks (on a per year, not per day basis).
I'm basically doing the same thing as you. One of my friends asked if I wanted to go to
Disneyland in early February but since I already have a January and a late February trip planned, I told her no. I've been actively telling my friends to not go to Disneyland because I don't have enough reservations to cover all the dates. That leads to less food spending at Disney from me, and fewer ticket sales from my friends and family.
My guess is that just before renewal time, they will open up reservations massively to Magic Keys. That way, when it comes time for everybody to renew, they will have forgotten this chaos and think Disney fixed the problem. Then Halloween and Christmas will come and Disney will severely limit reservations again.
Then give folks 5 cancellations? 10? Seems like you could bump the number up to deal with life getting in the way
Doesn’t shortening the time window make the problem worse? If you had a 7 day window with Dream key folks having 6 reservations at a time why wouldn’t they just keep 6 of the 7 days reserved on a rolling basis?
Because it is annoying to constantly log in and cancel reservations you don't want to use. Additionally, people will not feel pressured to book up dates months away with just the slight chance of going.
Hong Kong Disneyland originally had a 7 day window and one reservation at a time. After a couple weeks of fully booked days, it settled down. Now there is no reservation limit and no penalty for "no shows". You'd think this would lead to no reservation availability but dates sell out very rarely because very few people bother to log in to book dates they don't plan to go. With the "no show" penalty for Disneyland, it means that every time you book a day that you don't plan to go, you take a risk of forgetting to cancel. So the annoyance of constantly remembering to log in every few days to cancel will put people off from excessive bookings.
Part of the thing with the artificial shortage created by Disney is that frequent visitors will prioritize going to the parks on days they can spend more time in the parks (likely weekends) and avoid going on days they can only spend part of the day. So for some keyholders, instead of going Monday through Thursday after work to get on all their favorite rides with short waits spread out over several days, the limits push them to going on a weekend and do all of them on the same day with long wait times.
Everything said, I don't think a 7 day window would work for Disneyland but a 14 or 30 day window could alleviate a lot of frustration. The initial few weeks may be rough as the pent up demand finally has a chance to let itself out but I think it'll settle down into something more acceptable.
