I have taken my baby (and older children) twice to the Taba Hilton and had no problems at all.
The first time he was only 7 months so I took pouches and a cup which I washed in the free bottled water we were given, but he ate loads of the hotel's bread and bananas as well.
The second time he was 19 months and ate everything from the buffet. All the drinks were bottled/UHT anyway, and the hotel was so obviously clean and demanding about hygiene, we all ate raw fruit and salads with no ill effects. All guests were made to use anti-bac gel on their way into the buffet (and called back if they tried to slip through!), food handlers wore disposable gloves etc. The catering manager also offered to prepare food separately for anyone on a special diet.
I didn't hear of anyone else getting ill either. Part of the reason may have been that we went in December, when it was not too hot. Apparently dehydration makes you more likely to get ill. The high standard of hygiene was apparent throughout, not just in the buffet. It was a big factor in choosing to go back to the same place.
It was a wonderfully relaxing holiday. The all male staff were so kind and friendly, often whisking our baby away while we ate or stopping to play and chat with him. Many of them have small children they only get to see once a month when they have leave, and they are so natural with babies.
Another great thing about the Hilton was being able to have a room right on the beach (Nelson Village), so instead carting loads of stuff with you could nip back to get things as needed, leave wet/sandy gear on the room terrace etc.
Temp in Dec was perfect for babies, pleasantly warm but not hot in the day (21-24 degrees) and cool at night (cardigan/jumper over t-shirts).
