I'm planning to book a cruise on Jewel of The Seas going to the ports of: Copenhagen Stockholm Oslo Helsinki Tallinn St. Petersburg Does any one have any suggestion for excursions in these cities? I'm especially interested to know if a day trip to Moscow is worth the cost. Also, I've been reading descriptions of excursions on RCCL's web site & the references to walking & climbing steps. Walking long distances on cobblestone is absolutely no problem for me, but I do have problems with almost unending steep steps. A few steps in any one location is fine, but for instance, I had real problems getting to the top of Mt. St. Michael and the steps leading to the entry point of the toboggan rides in Funchal. No problems anywhere else I've ever been. Trying to compare what I've experienced, I also read RCCL's description on Pompeii which is described as having steep inclines to the area. In my opinion, it wasn't steep. I'll really appreciate any information anyone has to offer.
