Need to lose weight after travelling!!

Hey everyone. So I have been travelling for 3 years now in Greece, Mauritius, Tunisia and Australia and I have just been successful to work for Disney Cruiselines however all this travelling and having fun has taken its toll on my figure. I have lost 11kg so far (just over a stone and a half) and would love to lose another 1-2 stone. I am going home in 10 weeks to surprise all my fiends and family who I haven't seen since coming to Australia 15months ago. They think I am flying straight to Orlando for my training. So I have 10 weeks to get in shape!!! Please help me!!! I need MFP friends xx
