We would like to take a trip to Tigre and the Parana River Delta in Argentina . Please advise on how to get there, what to see and, possibly, where to stay. - Susan Rose-Smith

The Parana River Delta, about 30km north of Buenos Aires, covers 8000km² and is the world's only river delta that does not flow into the sea but into another river. The most picturesque way to get there is by train (known as the Tren de la Costa). It runs from Retiro (downtown Buenos Aires) to the Tigre Delta Station in 45 minutes, allowing passengers to see the Rio de la Plata coastline and dream of staying in one of its holiday residences. The cost is less than 50 US cents.

Other ways to travel to Tigre include ferries, taxi boats and taxi (around $30). However, the mode of transport is likely to be included in the package you choose for your trip, which is easier than trying to do it as an independent traveller. There are many tours leaving Buenos Aires on half- or full-day excursions. Most will include a ride on the train and sailing on the Parana River. Two companies you could try are You Say Hueque Tours ( www.sayhueque.com ) and the more upmarket Borello Travel ( www.borellotravel.com ). There are plenty of resorts in the delta, most of which offer all-inclusive packages for two or three nights. Among the best are the Delta Eco Spa ( www.deltaechospa.com ), Rumbo 90 ( www.rumbo90.com ) and Bonanza Deltaventura ( www.deltaventura.com ), an 1898 villa on a former fruit plantation.

We have a three-day stopover in Dubai in January 2012. We are two adults and two children, aged 12 and 14. Can you recommend accommodation in Jumeirah or a central location? - Shaun Ranchi

Many people consider Dubai hotels expensive, but you can find some bargains by opting for self-catering accommodation and using a discounted-sales website. I checked for options in January next year at www.booking.com, which can be set to give prices in rands.

A good budget option would be to take two adjoining studio units at the Ramee Hotel Apartments. Located in the Bur Dubai area, this complex offers a rooftop swimming pool, a gym and spa. The studios, which have a kitchenette, are priced from R354 per person.

One of the most popular options is the Golden Sands. A two-bedroom flat sleeping four costs R1068 plus 5% service charge per night. This complex, which offers a sauna, gym and free internet access, is minutes from the Bur Juman shopping mall.

If you want to stay at one of the big shopping malls, try the Ibis Mall of the Emirates. Although the rooms are small, they have air-conditioning and satellite TV. The best feature of the hotel is that it is located less than two minutes walk from the fabulous Mall of the Emirates, with its hundreds of shops and indoor ski slope. A room sleeping two costs from R506 plus 20% tax per night.

If you want to stay in Jumeirah, one of the best offers is the Regent Beach Resort. It is located on a safe and sheltered beach. Double rooms are available at www.asiarooms.com for R431 plus 20% per night.

We are looking for a campsite in or near Dublin. We will not have our own transport, so public transport to the city centre is a must. We need somewhere fairly comfortable, as we are hoping to stay for two weeks. - Heinrich Kirk

You can try the Camac Valley Tourist Caravan and Camping Park. Although it is in Clondalkin, about 10km from the city centre of Dublin, it is serviced by a bus route. If you like a country atmosphere, this one will certainly suit you as it lies on a 6ha site and adjoins a 160ha public park with fishing lakes. There is space for caravans and tents, and each site has water and electricity. Visit www.camacvalley.com or phone 014640644.

My six-year-old son and I are travelling to Phuket in December. We have a seven-hour stopover in Singapore. Can we leave the airport? Could you recommend something I could do with him, something out in the open where he can run wild after being cooped up on the plane for 10 hours. - Lezly Pretorius

A: While seven hours can feel like an eternity at the airport, it is not that long for a visit outside. It can easily take 30 or 40 minutes to leave the terminal, and once you have added the transport time to and from your destination to the fact that you need to be back in the terminal two hours before your flight, you may find that you only have three hours to sightsee or have fun.

You may therefore want to stay at the airport complex and enjoy the facilities there. In terminal two there is a playground made of tubes and plastic structures. There is also a kids TV room. Another play area features a 12m jumbo spiral slide. For a bit of nature, there is a Sunflower Garden, Butterfly Garden and Koi Pond with feeding times.

In the terminal outside of the transit area, there are giant inflatables for the youngsters to use up some of their energy. For a quieter time, there is a painting corner in terminal three.

But if you decide to leave the airport, a great destination is Sentosa Island. Here children can swim at the beach, meet pink dolphins, go to a butterfly park, zip over the rainforest canopy and ride on a tram. They can also visit Universal Studios Singapore, with its great theme park.

You could also visit the Singapore Zoo. This top-notch facility does not have its animals in cages. There is plenty of space for a youngster to run wild and see the excellent displays. Then there's Rainforest Kidzworld, which has a water play area, a petting zoo, a carousel and pony rides. You can catch a taxi to and from your destination.
