All I can tell you is what I have read elsewhere. Expedia does not have a regular transfer company. They use third party so don’t know who you will get, if it is included (I have read that it is not and it is expensive as Expedia needs to get their %), if it is shared and if so how many people you have to share it with. It’s just not worth all of the unknowns to me. I once took a transfer that was included in a package and we waited at the airport for stragglers, then it took 2 1/2 hours with all the stops. Very annoying.
If anyone has experience with Expedia please post.
