Hey, that's soon!
Sunday 23rd (half day?)
Take the 19/41 tram from your hotel along the river to the Chain Bridge. Take the funicular up to the Castle District. There is a lot up there so use a guide book like Eyewitness Guide to Budapest.
Then walk down and return to the hotel to get ready for dinner. I would take the 47/49 Tram to the first stop across the river and then go down the stairs under the bridge to the 2 Tram. Two stops down is the main part of the Corso. Eat outside at one of the many cafes and enjoy the view of the Castle on the other side of the river.
If you are tired go straight home, if not, get back on the tram to its end stop just beyond the Parliament, then walk to the 4/6 Tram, cross the river to Buda and ride the 19/41 home. It's a great relaxing scenic tour. Especially late in the day.
If you are up to it, from the first stop behind the Parlisment you can walk back to the river, go down the stairs to the "Shoes on the Danube" memorial.
Jewish Budapest. From your hotel the 47/49 Tram 3 stops, then a short walk to the Great Synagogue (take the tour), then use the guide book for the other sights like the Holocaust Museum and Rumbach Synagogue. All sorts of good places for lunch, just choose one and walk in.
After lunch walk through the Gozsdu Udvar (courtyard) and on to the Opera House on Andrassy ut. Take the M1 metro to Heros Square, City Park. Walk back down Andeassy ut for the Architecture and atmosphere.
At the end of Andrassy walk to tour left and you will see the 47/49 Tram that will take you home.
Dinner, see the list I will post last. Or an evening dinner cruise.
47/49 Tram to opp side of river and the great Market Hall. Then walk the length of Vaci ut and follow your map to the Basilica. Plenty of stops for lunch.
From Basilica walk to the end of Andrassy, take the M1 to the Oktogon, then a short walk to the House of Terror. Its 2 hours to do right.
Back to the Opera, cross Andrassy ut and go in 2 blocks to Kadarka Wine Bar and cool off.
You know how to get home.
Wednesday 26th leave.
