Upcoming trip to France in July 2-8.
Do we need to prebook:
1) round trip train travel Paris to Bayeux (single day travel: wife has wanted to see Bayeux tapestry for a long time).
2) Disneyland Paris tickets (1 day tickets as a treat for the kids)
3) 1 hr Seine River cruise (not dinner)
I've seen various answers and am confused if these are likely to sell out or how much prices rise closer to the dates.
