Yes, all the nice and half nice routes have tolls. You are doing the usual airport to Disney trek. Celebration and (former) Splendid China are "just past Disney".
If you take the north airport exit, left at first light, bear left, go about a mile to next light where you take two lefts, you get onto Rte 528 (Beeline) then pay the one and only 75 cent toll, then left onto I-4 west (southwest), follow I-4 all the way to 192, then you are practically at Celebration.
From I-4 west approaching the 192 interchange you go east on 192 to Celebration office complex and then main town entry, or west on 192 for Splendid China.
You will hit traffic on I-4 if you arrive at MCO at the PM rush hour. The other major route, south airport exit to Rte 417 (Greene's Way) eventually reaching I-4 avoids most of the traffic but the toll is about $2.00, bring quarters for exact change at some booths.

Returning up I-4 to 528 (Beeline) east get off 528 at Exit 9 Tradeport, left at ramp bottom, get into middle lane, cross under (excellent gas station right there although not quite as cheap as Hess stations inside WDW), middle lane becomes required right onto McCoy, about a mile to Semoran which is airport entrance.
