Toys R Us

I feel like my questions always seem trivial but I have read so much and feel I have a good grip on the "big stuff" so now it's the small details that I am worrying about. We are hoping for my husband's visa le soon and at least to arrive in the next couple of months.
This will be our first time being overseas for the winter and I am already thinking ahead about December gifts for my kiddos.
My boys love Legos and I am wondering if they are readily available at the Toys R Us in Saudi? Is there a decent toy selection at the Toys R Us or mostly off brand items? My daughter is into My Little Pony and all of the Disney Princesses, are these available?

Thanks so much in advance!!!!
