I am contemplating a WDW vacation from Nov 15-20. I have priced/availability for Pop, and it fits my budget. I would like to book Room Only, and purchase a 4 Park Magic ticket. Looks like this would save me money. Down the road, how easy will it be to link my ticket on MDE? Normally I do a package, and the travel agent does all of this for me. Even a Memory Maker, if I decide to buy that.
