DD2 has recently transitioned in the toddlers room, and she still needs 2 sleeps a day. They can't put her down for a second sleep in the toddlers sleep in the afternoons due to staff numbers, but as the babies' room has the staff capacity, they take her in there and she has 2nd sleep there. It works well for Emily and the staff, they don't mind doing it.
I hope something can be worked out.
