Go on - be a devil and hang the scheduling - do both - they're only half hour each - sure you can fit it in.
We were only going to do Lion King, but then on last day, just before leaving, there was enough time after the parade at 4 to make the 4.45 showing of Tarzan.
Glad we did, they're both great, Lion King for songs, Tarzan for acrobatics.
