The biggest problem Disney World has with their reservation system for passes and resorts

Going to Disney World or Disneyland can be a hectic, time-consuming, often headache-inducing event that ends with spending a lot of money and even more time. Disney is missing something.

"Finally!" Your kids scream as you tell them you are taking the family to Disney. Now, it's time to get everything set up and ready to go. You have your vacation week scheduled at work and now it's time to dive in and make your reservations. Not so fast. You are doing this wrong.

The first thing you have to do is scroll through the available resorts to book your stay. Tickets are easy enough but you still need a place to stay and Disney, like most hotels, has an ebb and flow to their pricing structure.

I won't dive into the absurd and ridiculous pricing that seems designed to keep most families off property but I will say that one thing is missing that would at least make this whole thing easier.

Disney needs a much better calendar on their app and website!

I will admit it, I loathe the Disney Website. The navigation is easy enough but if you are trying to book a stay at a value resort, an RV spot at the campgrounds, or just looking for a reasonable stay, you will be met with messages telling you this.

"This property is not available for the dates or party size you have selected."

There is nothing more annoying than this, sorry Disney but you really need to fix this. Why? Because there is no alternative. There is no magic button that you can click on that will show you a calendar of availability. Instead, you have to manually put in new dates or select from what is available.

For most vacation planners, scheduling your vacation early allows you flexibility. Looking at a calendar that shows when a certain resort is available makes a lot of sense that Disney isn't providing.

Let's look at the campgrounds. I have tried over and over again to find the cheapest RV spot but if I click on one week and it's not available, I have to manipulate my search. In some cases, that RV spot that I was hoping to land might actually be available for all but one day. In other words, if I shorten my trip by one day, it's open. Maybe I can shift my vacation by a couple of days to get the spot I want without being forced to reserve a higher-priced pad.

The same with the resorts. Click on a date range and the All-Star Resorts may not be available and you could be forced to stay at one of the mid-tier resorts for a lot more money.

A calendar would be so much easier even if that calendar only showed a six month window. If it did, you could simply click the calendar and say, "Oh look, two weeks later and the value resort is available. I'll schedule my vacation then!"

A company the size of Disney should be able to provide this simple access to its available inventory. It's a simple addition that could not only help guests plan their vacations better but also save them some money they can spend inside the park.
