Hi! I will be in Frankfurt from May 1 - May 4 and was wondering if anyone had advice on where to stay or what to do. I am looking right now at the Westin Grand or Le Meridien. Im not familiar with the elite offerings of these brands because they are former SPG and I have been strictly Marriott. One of the days I think we would like to take a train to Rudesheim for a river cruise and maybe a visit to a winery. If anyone has any suggestions, please let me know. Thanks!
