We stayed at Jambo earlier this week for a quick 2 night trip. Booked a standard room, got a partial savannah, of 2 different savannahs. The room itself wasn't dark, but the hallways certainly were! The room was decent sized, the bathroom definitely a bit bigger than value bathrooms. We were in 4574 (I think), a bit of a hike down the halls to get there.
The people upstairs were very noisy the first night...we could hear the adult male encouraging the children to jump from bed to bed and to the floor, and when we complained, we were told at the desk they couldn't do anything about it until 10pm (this was 9:30, with a 1 year old asleep). At 10:15, when it still hadn't stopped, I went back to the desk and the CM said "well, I'm not sure what you want me to do about it." I asked for a manager, and finally spoke to one about 20 minutes later. The upstairs noise was gone by the time I made it to bed about 11:30, but then we had a knock on the door. A CM, looking very confused, said we called down for an animal guide, and brought it to us. No one called about the guide...we think it was the upstairs people being jerks because they got called out on their noise. No noise the next night though.
Also, the bus to MK was bad. We waited through 3 buses to AK, 2 to Epcot before one came for MK...on a EMH morning 8:15 am. We were there 40 minutes waiting. It was the same driver that was so slow when we were there in October, waiting on a bus from Epcot to AoA...that was an hour wait midafternoon! He let half a family on the bus, but then shut the door on the dad and started to drive off. The little girls freaked out about dad, and the mom told him to stop and let dad on, but the driver said no room. He did stop and let the family off, but the girls were in tears by then. We did complain to the transportation guy we saw at MK at our drop off point, and I did call transpo about the driver (again) when we got home on Wednesday.
We only ate at Mara for dinner one night (ate at Sweet Tomatoes on our arrival, and at the parks the other meals). I ordered a Chicken BLT, and received a chicken and lettuce on a ciabatta. Not what I ordered. DD had gone down to get the food, and ordered it correctly (on the ticket) but not the right food. Took it back down and they gave me a bit of guff before replacing it.
Other than those 3 things, we loved the resort.
