Yes, side trips are allowed as it is after Hajj. The reason Falcon Travel prefers side trips to be after Hajj, is so you can arrive with the Group to Hajj, and also usually Tickets during Hajj season are very expensive but when we get them in bulk we get a better deal than getting a single ticket. That is why we highly recommend that if you don’t have an urgent reason to travel before Hajj, then delay your side trip until after Hajj.
