Never been to the Westgate but..

High Roller and Neon Museum are both worth it..there are High Roller discount tickets everywhere. If you go to Harrah's to buy the High Roller tickets, they often have deals going.

For your first "Cirky Solay" show, you may want to try the original one..Mystere..and since it has been out for years, there are great deals all over on that one..
