I hate to be a kill-joy...but I would seriously suggest that anything that is knife or sword or pistol shaped be sent on ahead via either parcel post or UPS. I am not sure what the policy or procedures might be when checked luggage goes through their Xray and they see what they believe to be weapons. I do know that they scan checked luggage now.
The hotel will accept packages sent to your name with a hold for arrival on such and such a date.
I always did that with Retired Racer's product and Swap and Sell pieces when I didn't drive. The cost was well worth it for the convenience of safe, INSURED, shipping without baggage handlers snooping , bags going astray and/or being tossed every which way without insurance or the type of packaging that we use when we ship our treasures.
I would much rather trust my valuables to one of the shipping companies who allow me to pack them, and allow me to insure them, than to any of the airlines today.
Can you imagine the scene if you were pulled off of your flight and taken into an iterrigation room and had to explain why you were carrying a fake pistol or a sword? Do you think that going to a party would cause one of the rent-a-cops to quickly say"oops, sorry, let's hold that plane and get you on your way"?
As I said, I hate to be a kill-joy, but.......
How I wish I were going to be there with you!
