Lets Party And Be Merry -Part 1

part 1

משנכנס אדר מרבים בשמחה

The Rema (O.Ch. 493:2) writes that on Lag Baomer we  

increase with a little Simcha "ומרבים בו קצת שמחה"

When Chazal tell us משנכנס אדר מרבים בשמחה, there is no mention of קצת. 

It seems the שמחה of Adar's arrival is greater than the שמחה of Lag Baomer. 

Wouldn't it be more appropriate, when Adar arrives to at least do the same if

not more and dance to the music all night long, make a Hadlaka, party & be merry etc.

*WHY NOT ? 

*this question is in need for an answer
