Not sure if this is the right place to ask but il try it out and if it gets moved i know why.

So im a average factory worker living in Sydney married with two daughters 4 and 2. The first was smooth sailing just like the doctor ordered. The second wasn't so great. Half way thru we get told she's got severe cleft lip and palate both sides we going to be in for a tough ride.

Nearly two years past its hard honestly she also has a chromosome disorder and for unknown reasons she cant eat or speak. Weekly visits to the children hospital in Sydney seeing sick kids is the worse of the worse. We need to get away . So i start planning and looking for ways to travel cheap and enjoy a little more. I joined a few hotel loyalty programs somehow got invited for a diamond trial with hyatt. Once i got the diamond benefits i tried status matching hilton came thru i haven't tried anyone else.

Now with the status of diamond i read thru pages of how to get the cheapest accommodation and i came across the stay certificates. I used a few and saved the rest for the trip which i planning for the whole family to Europe next may/june.

Next came the flights and i discovered US DM and checked for the flights and asked questions. I joined myself and wife into the program and waiting for promotions or anyway to earn miles cheaply. I can across the grand slam promo people are waiting for. So now im trying to get organized for that . Im hoping to achieve the 36 hits (In theory) needed to get the 100,000 bonus miles. All together i need 480,000 to flight Sydney to Europe. Stopping anywhere on any flight practically any time as long as we are together .

In Europe the only thing i want to do is take the kids to euro-disney and my wife is from sali so she wants to go to Croatia.

So the help im seeking is how to earn points for stays with hilton or hyatt or any hotels . How to make the most of the status of have (hyatt diamond already expired in plat) so hilton gold. Also how to earn enough miles for the flights. I have looked at buying them but 27.50 for 1,000 its just too much.

In regards to being in australia how can i make the most to get the 36 hits to get the bonuses of the GS 2011 promo thats suppose to be in september. I cant join any credit cards i joined the qantas club for free which im earning QFF but 1 point after i spend $30 so its going nowhere.

Also one thing i need to know my daughter is tube feed thru a pump that connects to her tummy without it she wont survive can i take that on board to fly ?

I also thought about buying cheap points from the cc but havent got enough posts yet to have access . I daily read the points guy /frugal travller and miles high / view from the wing nothing that i have seen can help me much being outside the US.

Im not a business owner i dont get paid to travel the world or stay at fancy hotels my education stopped at the end of high school so i know im way in over my head . Every time i try to post something or chime in i get bad feedback and was told to post else where. Which is here i dont know where else to go.

Any help is much needed and appreciated.
