Sandra and I have taken 10 wonderful Tours with S.D.T.'s starting in 2000 and have never travelled with any other company.This year was to be the "best" and covid 19 spoiled our 55th anniversary and our much anticipated "Tulip Time River Cruise".Hopefully we can make it next year.My only disappointment has been the way in which rooms have been given out alphabetically, we have had the displeasure of staying in some dank cellars to distant cabins far from our fellow travellers due to the "W' in Willis,surely a better method of room allocation can be found.Your careful consideration would be appreciated.Sincerely Leonard & Sandra Willis.
