Myself and my immediate family UK General Visitor visa was refused for insufficient funds evidence

We applied for UK General Visitor visa for 10 days, and were refused:

• You have submitted an employment letter to confirm your occupation in KSA. Although your employment letter details your income, the bank statement you have submitted does not reflect your income. You claim an income of SAR xxxxxx. Whilst I acknowledge you may not be paid directly into your bank account, you have not demonstrated regular deposits in amounts matching your income. As you have not substantiated this income through clear evidence I consider that the documents you have submitted, in isolation, do not reasonably demonstrate your own circumstances in KSA.
• As I have been unable to ascertain your financial circumstances and specifically your income in KSA, I am not satisfied that you have reasonably demonstrated that are travelling to the UK solely for the period and purpose you state (paragraph 41 (i) and (ii)). I have therefore refused your application because I am not satisfied, on the balance of probabilities, that you meet all the requirements of the relevant Paragraph of the UK Immigration rules

1. We are all Indian nationals living in Saudi Arabia, and applied there.

2. In 2012, I applied for a Family Visit C visa for UK and received the visa but did not travel.

I did not bother much as I was a bit overconfident that I would be granted the visa.

I am thinking of reapplying and will do the following:

1. Submit the payslips (that will show the Gross Salary and the amount deposited in bank account). A big reason from the mentioned salary versus "deposited in bank amount" is that I get Housing Allowance for six months in January and June. This is deducted from salary every month, and the deposits will always be less than what is shown on company letter.

2. Also I got bonuses twice in span of four months, and it was through bank deposits by company, and I will also get a company letter justifying the payment made to me.

My intention is to visit London tourist attractions and my uncle, who is recovering from cancer treatment.

Also, I want to do the following:

1. Instead of hotel booking (as in the previous application) I plan to get a letter from my uncle (father's real brother, who is a UK national) for accommodation. (This would not match with previous application, where I showed hotel bookings.)
2. I am thinking of applying for myself first and once I get my visa I will apply for my kids. This will be again mismatch, as in previous (rejected) application I said that my wife and kids would be travelling with me.

Again I will state that I have no intention of staying in UK, as I have a fairly good job and I am sure I will not get such a job in UK.

Can anyone suggest what should I do especially on the two issues (no hotel bookings but letter of invitation for accommodation and food, and applying myself first and then for the rest of the family)?

This time I will try to be meticulous as I do not want to face another rejection.
