Just got back from a 12-night stay. We were in Sago Cay, garden view (but our view was really the monorail -- quite close).
It was a good vacation overall, and the GF was beautiful, but we did have a few issues.
The first night, our 2-year-old somehow locked himself in the bathroom. We could not pick the lock. It took them a bit longer than I'd like to send someone to the room with a key for the door to get our toddler out of there. He was upset. I was anxious.
Later on during our trip, my husband got stuck in the bathroom! The door wasn't even locked this time, but totally jammed. We had to wait like 20 minutes after I made a phone call for someone to come in and get the door open. He supposedly fixed the doorknob, but I was too nervous to even close the bathroom door after this. This happened the night we had a dinner reservation at 'Ohana. We had stopped back at the room to shower and freshen up after sweating in the parks all day. We ended up late for our reservation because of this happening, but luckily had no issues being seated.
The day before checkout, we had no housekeeping service at all. We needed it. I don't care so much about unmade beds, but my son is in diapers so the trash needed to be emptied (it smelled...), we needed a towel refresh, etc. We didn't know they never showed until we got back to our room late at night and needed to get the kids to bed right away. We were out most of the day -- gone by 8am, and although I relaxed in the room for 1-2 hours in the late afternoon while my husband was at the splash pad with the little ones, no one knocked on the door while I was there. The "do not disturb" door signs were gone by this point.
Also, as beautiful as the resort is around Christmas time, it truly is busy. Especially in the evening, around the time people are there for dinner or going to MK for fireworks, waiting in the long security line at the monorail was kind of inconvenient. We got off the elevator with our stroller, and the line extended beyond that point. I imagine they could figure out a way to implement a separate line for GF guests and one for those that are just visiting during peak times?
Positive notes: our room was quiet, upper floor request was met, beds were comfortable, location was convenient to bus stops and Gasparilla's, resort food was good, splash pad (which my kids loved) was often empty, fireworks view from the marina is always great, cast members were friendly, kids got to meet Santa right there in the lobby on Christmas Eve.
