I am taking advantage of the great Mousesavers deal at the Royal Plaza at DTD this December-$69/night including breakfast! I haven't stayed in a non Disney hotel in over 7 years of Disney trips. Since this is a short stay with just me and my DSs, I thought we might try it. Just wondered how nice it is? How are the busses? I love being able to walk to DTD.
I stayed @ The Plaza 1 year ago,and here are i little of what i thought.
We had a tower room,(2´nd floor, thats the first room floor )

The room are very large for an Orlando area hotel,(have i learned).
It has an "roman tub", meaning the tub are square,and pretty large.
The balcony are a joke,as the size of it are so small that you can stand on it,but not turn around.

The hotel looks good,and everything was clean and the staff was friendly.
The Disney buss leaves the hotel every 30,min.
There are 1 bus for each park, Ordinary, but at slow times 1 bus goes to Two parks.
The bus also picks up people at other DTD hotels,so it can be Your not getting a seat.
You can walk down to DTD Marketplace ,they got nice sidewalks,and the walk will take about 25,min.
You can also walk "the other way"(15,min),then you come to "the crossroads",where there are a big grocery store,and many eateries. McDonalds,Pizza Uno,Taco Bell,and many others.
You have an Magical Time.
Roger.
