Answering question anout river cruising. We Went on a 2 week river cruise last autumn, apt, an australian company. Budapest to Amsterdam. Majority of Passengers were australian, all Very friendly. . It had no formal nights And dress is what you would normally wear on holiday. Its an expensive option though cost more than twice as much as a caribbean cruise we took in january (treating ourselves ) and there were things i didnt expect, ie 70 locks from hungary through austria, each one sometimes took over an hour to get through. All goes dark. The top deck was closed for 6 days due to low bridges and when we docked it was side by side with other boats which meant pulling curtains, putting lights on and being unable to use our balcony (did say we were spoiling ourselves) because the boats are parked so close together. A nyone with mobility difficulties would find it awkward as you need to climb up and over up to 3 other ships. However we did enjoy it but the few brits onboatd were astonished to find those whose long haul flights from australia cost considerably more than our local flights had paid less than we had, and they had an extra week included in the vist. Finally i never got a decent g and t, the tonics were always flat. ?Gin was ok though? Food good, staff nice. I just wish i had been warned about locks, sundeck, privacy,and tonic?
