I'm looking at a Val d'Europe partner hotel for next summer - hoping to get a package. However, the package prices for my dates have vanished for all the partner hotels (I got them mid-day, but when I tried them again later that night, there were no offers for any of the partner hotels!) I'm still holding out hope, but if we can't get a reasonably priced package, I might look at the Ibis and buying tickets separately.
I'm hoping the RER to and from Paris is reasonable for sightseeing there. I'm just hoping I can find a decent rate - without it, DH might nix Paris entirely!
