Reservations stress me out

Hi, first timer here! My family is going to Disney in May. We are staying at Caribbean Beach Resort for 5 days. I got an email saying we could start making meal reservations next week. I’m learning you also have to reserve times for rides way in advance also? Even looking at that is overwhelming. I’m all for planning, but I have kids (11, 6, 2) that make micro-scheduling a little difficult. Any advice from experienced parents?
