Catherine,
First off, thanks for the compliment!
Now let me be honest with you. I don't really know exactly what rooms have trundles, and which don't. Some recent room renovations have probably mixed that up a bit anyway, so you may not have much of a choice there. But if you do, here is the order of buildings that I prefer in the Port Orleans Riverside resort. Note that I prefer the Alligator Bayou ambiance a bit to the Magnolia Bend, though both are really great.
These are the buildings I request, in order of preference;
- Building 14
- Building 18
- Building 15
- Building 27
- Building 85
- Building 90
- Building 95
Now I know that there are some trundle rooms up in the 34-35 range (far away from main amenity building), but even if you are out there, don't let it bother you. You are still near a bus stop, and it is not as long of a hike here to the main building that as some other resorts!
Have a magical vacation!
