It's not clear to me when tumbling if your entire move is reduced by half, or if only the squares tumbled through cost double.
For example...
A character with 30ft move speed tumbles through 1 square (5ft) as part of a single move action. Can that character only move a total of 15ft during that move action, or does the tumble use 10ft of the 30ft?
