there is just my self and kathy comming to your hotel, My son his wife and children  are in side also they have got a villa at olive grove by managvat.

My attempt as learner:

Sadece ben ve Kathy senin oteline geliyoruz, oðlum, eþi ve çocuklarý Side´deler, ayrýca Manavgat´Ã½n yanýnda, onlarýn zeytinlikteki villasý var.

Hý tomac, shouldn´t it be ´to the hotel´

Sadece ben ve Kathy senin oteline geliyoruz, oðlum, eþi ve çocuklarý Side´deler, ayrýca Manavgat´Ã½n yanýnda, onlarýn zeytinlikteki villasý var.

(I made a similar mistake in my translation attempts yesterday)

Also I think ben should be beni to relate ´I´ to the verb geliyoruz. But as I´m a learner I´ll wait for someone better to confirm this.

Otherwise your attempt is very similar to what I was about to post.

Thanks for you corrections, Henry! What´s strange, I had seen your post few minutes before and then I made the same mistake

I think there should be "ben", because "ben ve Kathy" are the subject, not the object of "geliyoruz". I guess it could be also "Benimle Kathy", but I´m not sure which one could be better.

thank you tomac and henry

"benle Kathy" ,"benimle Kathy" possible as well.
