We stayed at the Home2Suites in Flamingo Crossing in December 2021. Also have stayed three other times at the Springhill Suites nearby. We also have stayed multiple times on-site at CSR, CR and WL.
We always drive from Atlanta, so we had our own car for transportation.
The rooms there are equal to a Disney Moderate, we had a two-bedroom suite with a huge amount of space. Extremely comfortable. Breakfast was standard free hotel fare, nothing to write home about but they have freshly made-to-order Mickey waffles.
We had breakfast at the hotel, bought lunch at the parks, and while leaving mid-late afternoon, ordered dinner from one of the many restaurants on 192 on our phone, picked up the order, and had dinner back in the room. Gave us a chance to refresh, visit the pool and then go back to the parks in the evening. Saves a ton of money avoiding Disney Dining.
Flamingo Crossing is technically on Disney property and is a 10-15 minute drive to all parks but MK. You can be waiting for a bus, especially during non-peak times longer than it would take to drive to/from Flamingo Crossing. Coming in on Western Way is quick and simple. The only time when the traffic is busy is about 5-6 PM when Cast Members are heading home. Only going to the MK and having to go through the TTC is a major expenditure of time.
If you have your own car, you are probably saving time vs using a WDW bus system to get to the parks. Yes, you do have to park the daily parking fee but the room and meal savings more than make up for it.
Yes, you have to leave the bubble but Disney has also reduced the perks and benefits allocated to the Value and Moderate resorts.
The biggest drawback for us was the inability to split up and have our family go their separate ways. We had a couple of times when someone was tired and wanted to head back to the room while others wanted to stay a bit longer in the park. When we stay on-site, it was easy for someone to head back to the room early. Staying off-site, and going anywhere was typically an all-for-one, one for all situation.
The single biggest benefit is the early entry for all resort guests. But we are not a rope-drop family so it is not of value to us.
