Finance and money forum

hi all, my first post on this site after many days reading some of the great info on here. my question is me and my girlfriend plan to travel for 4months. the itinary we roughly went for is as follows.
1] jo'berg- one week for a safari
2]thailand/SE Asia 6 weeks
2]sydney/australia 3weeks
3]auckland 2 weeks
4]fiji 2weeks
5]los angeles 1 week
6] new york 1 week

This is just a rough estimate doesnt have to be matcheed perfect.
Do you think we are trying to fit to much in? we also plan to budget £7000 for the trip for accomodation,food,sightseeing and internal travelling.does this sound about right??cheers
