US trip itinerary (this Jan)

[Obiter]

Hi, Just thought I’d post my itinerary up and see what people thought. I’ve never been to the US. I haven’t booked anything yet – haven’t even bought my flight to the US but will very soon.

05-Jan Atlanta
06-Jan Atlanta then bus to Orlando
07-Jan Orlando
08-Jan Orlando then fly to Cayman Islands
09-Jan Caymans (I have a friend there, so no accommodation costs etc)
10-Jan Caymans
11-Jan Caymans
12-Jan Caymans
13-Jan Caymans
14-Jan Caymans then fly back to Orlando
15-Jan Orlando
16-Jan Orlando
17-Jan Orlando then drive down to Miami
18-Jan Miami
19-Jan Miami
20-Jan Miami
21-Jan Miami then fly to Washington DC
22-Jan Washington
23-Jan Washington then bus to New York
24-Jan New York
25-Jan New York
26-Jan New York
27-Jan New York
28-Jan New York
29-Jan New York then bus to Boston
30-Jan Boston
31-Jan Boston
1-Feb Boston then bus back to NY and then fly to LA
2-Feb LA
3-Feb LA
4-Fed LA then fly back home to Sydney.

Any opinions? Doable?

I've estimated this trip will cost US$10k doing the normal touristy stuff (and also a skydive in Orlando and learning the scuba-dive in Caymans) and staying in cheap hotels or hostels.
