I have been off the boards since March 1st.....my husband had a mass in his stomach lining and it literally put my entire life on hold....I was consumed with worry....anyway all is good now....it was a hematoma, no tumor, no maligancy.....now moving forward with plans but I am behind a bit and I was so on top of it.....anyway we have ST. Petersburg booked with SPB and Berlin as well......I booked all Palo and babysitting......what I need to know is what to do in other ports? My diellema is we are 3 adults and 4 kids...ages 9,5,5 and 2.....the cards seem the best bet but really not liking the idea of public transport with kiddos...think they would be better off on Ho HO buses.....also thinking we should cards on top of this to cover admission everywhere....I saw that some of the hohos have family tickets....would really love thoughts on this so can move forward with planning.....also wondering if I should pre pay for all of this before we go.....if so when should I buy we leave for London on June 15th.....also when do I need to purchase our 7 days London cards......please help me decide......or send links with the answers....i know purchasing both seems redundant but don't think I want to navigate public transport with 4 young kids.....
