I would definitely still make the ADRs..especially the ones you really want! You can always cancel them if you have to, but this way you will have your ADRs secured, as you very well may not be able to get them later. I booked all of our ADRs, and we plan on changing our trip to 3 weeks later, if a new offer comes out for that time period (ex,
free dining). I have also begun making ADRs for the later time period and will cancel one set of ADRs when we know for sure which ones we will be using! I worked so hard planning and figuring out ADR schedules, there's no way I was going to lose them all by moving our trip...so I planned both times and will cancel the one we don't need!
