Hey Karin,
I figure 4-5 days in EP, and then 4-5 at DLP. In this way I can justify flying : ) We have never been to DLP or E.P. and normally to WDW we go at least 2.5-3 weeks. It seems based only on my short time of research that a week at DLP is pushing it, so I thought why not try to add on a trip to E.P. to stretch it out to 2 weeks. The kids are very excited about DLP, but not so much on E.P., so I thought to do E.P. first, and save DLP for the end.
I may just have to get over the fear of renting a car in a foriegn country and bite the bullet, rather than lugging small kids and suitcases through busses and trains..
Thanks as always for being so knowledgeable and responsive!
