The reviews say it all - here's why you should work with us: How Good are Yombu's Entertainers? Our clients rate us as the best kids party entertainment marketplace, with consistent 5 star reviews and regular re-bookings. Is it Easy to Book? Super easy! We have made it all easily accessible by allowing clients to check our live calendar, book and pay, plus chat live to entertainers, all from their Yombu account. What if I Need to Make Changes to My Booking? As with booking, you can also reschedule or cancel if something changes at the last minute. You can also easily refund yourself without fuss.
